7 July 2016: Opening of CryoLab for Extremely Sensitive Electronic Measurements

The CryoLab of TU Delft's Faculty of EEMCS has been opened on Thursday 7 July by the dean Rob Fastenau. TU Delft scientists from the Tera-Hertz Sensing Group, Jochem Baselmans and Akira Endo, will be leading a team of young scientists and engineers working in the lab on astronomical instrumentation. The first instrument, DESHIMA (Delft SRON High-redshift Mapper), is being developed to be operated on the ASTE telescope in the Atacama Desert in Chile. The goal of the research is to create 3D charts of so-called submillimetre galaxies that, in contrast to 2D charts, also show distance and time.

The large number of superconducting detectors, and the advanced electronics developed at SRON, allows DESHIMA to map a very large volume of space at once. While Endo leads the development of DESHIMA, Baselmans will soon install the next cryostat for testing novel THz array antennas, that will enable his upcoming instrument MOSAIC to target multiple galaxies at once. In the future, the CryoLab is envisioned to also host new coolers from QuTech. Superconducting electronics used for astronomical instrumentation and quantum electronics have much in common, because they both push the limits of what can be observed.

Congratulations to Prof. dr. Sarro with her royal honour

Professor Lina Sarro, professor of micro-electronics at the Faculty of Electrical Engineering, Mathematics and Computer Science, has been made a Knight in the Order of the Netherlands Lion, in The Hague.

She received the award because of her original research that resulted in a large scientific body of work and because of her in-depth involvement with her many students. Her pioneering work in the 1980s in the field of infrared sensors led to international acclaim. Since 1987, she has been in charge of research into micro and nanosystems (MEMS and NEMS) at the Else Kooi Lab, which was known previously as the Dimes Institute for Microsystems and Nanoelectronics.

Professor Sarro has published more than 200 articles in scientific journals and has received awards for her work on several occasions. In 2004, she received the Eurosensors Fellow Award, in 2007 the AISEM Career Award, and in 2012 the IEEE Sensors Council Meritorious Award. She is also a member of the Royal Netherlands Academy of Arts and Sciences (KNAW) and a fellow of the Institute of Electrical and Electronics Engineers. She has been praised on account of both her scientific work and her unfailing commitment to providing teaching of a high standard.

To her students, from both inside and outside the Netherlands, she is a figurehead. This applies perhaps in particular to female students and academics. In 2005, Professor Sarro became the first female to join the TU Delft Council of Professors. She is dedicated to emphasising the role of female scientists, in the conviction that it is a waste to use only half of our scientific assets. Her outstanding scientific reputation ensures that her voice is heard in this, and in other issues.


Nuria Llombart awarded by ERC grant

The European Research Council has awarded associate professor Nuria Llombart Juan of the Tera Hertz Sensing group a prestigious starting grant (1.5 million euros) for her research proposal Lens antenna arrays for THz coherent cameras.

The THz region was, traditionally, limited to applications in radio astronomy and space science. In recent years, THz systems have expanded into many more areas of science, defense, security, and non-destructive industrial applications. Microwave based THz cameras have demonstrated the highest sensitivity at large distances. However, their current state of the art is comparable to the first analog photographic cameras characterized by long exposition times. Two fundamental problems have to be addressed to change this situation: technologically, there is the lack of integrated coherent arrays with high power and sensitivity; and theoretically, a field representation to characterize analytically these systems is missing.

I propose to tackle the technological problem by exploiting the coherency between small antenna arrays coupled to actuated lenses to overcome the sensitivity problem and achieve instantaneous refocusing (i.e. zooming). The proposed antenna technology is based on a recent breakthrough that I pioneered: micro-lenses excited by leaky waves with seamless integration in silicon technology. This antenna enables the fabrication of large flys eye cameras in just two wafers, and promises one order of magnitude better scanning performances than previous solutions. An analytical model to investigate the electromagnetic response of coherent THz arrays is the enabling tool for optimizing the camera performances. I will develop this tool by combining advance spectral antenna techniques with coherent Fourier Optics. This model will not only be used in new beamforming techniques, but also for the characterization of future THz telecommunication links.

NWO Veni-grant for TU Delft researcher Dr. Daniele Cavallo

Dr. Daniele Cavallo has been awarded a 3 year NWO-Veni grant to develop integrated technology solutions for generation and detection of Terahertz (THz) waves. He is a post-doc in the THz Sensing group, within the department of Microelectronics at Delft University of Technology, The Netherlands. The title of his proposal is Efficient On-Chip Antennas for Terahertz Applications.

Terahertz waves
THz radiation has ideal properties for communication, security, imaging, and spectroscopy applications. THz waves penetrate through clothes and plastics and can lead to security scanners with new capabilities; thanks to their huge bandwidth, they can also enable ultrafast wireless communication, providing data transfer with unprecedented speed. Despite these attractive properties, THz radiation is scarcely used due to prohibitive costs and complexity of current systems.

Integrated technology
Integrated technology promises affordable and compact THz systems, to enable their use for viable applications. However, realizing a workable THz silicon chip is very challenging, because of the limited sensitivity that can be achieved (as detector) or the limited power that can be generated (as source). These limitations are largely attributable to the poor performance of integrated antennas, responsible for the conversion between electrical (on-chip) and radiated (off-chip) signals.

Enhanced radiation from chips
To improve the performance of on-chip antennas, Cavallo proposes two novel concepts: (1) connected arrays, i.e. multiple antennas connected one to another to overcome the disadvantages of isolated antennas and enlarge the bandwidth; (2) artificial dielectrics, i.e. materials engineered to have properties that may not be found in nature, capable of enhancing the radiation. His approach will solve the inefficiency problems of silicon-based antennas. This will result in sufficient sensitivity/output power of THz chips to enable their use for real-time security scanning and ultra-fast (terabit) wireless links.

Innovational Research Incentitives Scheme
The Veni grant amounts to a maximum of 250,000 Euros and is one of the three types of grants in the Innovational Research Incentives Scheme. The two other grant types are the Vidi (for experience post-docs) and the Vici (for very experienced researchers). The Innovational Research Incentives Scheme was set up in cooperation with the Dutch Ministry of Education, Culture and Science, the Royal Academy of Arts and Sciences, and the Dutch universities.

    Flexible bioelectronic medicines

    Abstract: Bioelectronic medicines are the next generation of neuromodulation devices: small active three-dimensional neural interfaces able to modulate nerve activity by targeting a specific neural region. They aim to treat a number of conditions, such as diabetes and asthma, in a tailored (per individual) and reversible fashion, avoiding the side effects of conventional drug-based interventions (pharmaceuticals). They achieve so by recording signals from the respective nerves, extracting information and using it as feedback to electrically stimulate the neural region in a closed-loop manner.

    Current technologies for active implants have not yet managed to achieve the miniaturisation and integration levels required for the development of bioelectronic medicines. For such breakthrough devices, novel concepts need to be explored, developed, and tested.

    In this talk I will present my current activities as well as my vision on realizing the first flexible three-dimensional graphene active implant, for safe chronic neural stimulation and recording from the peripheral nerves.

    Cryo-CMOS for Quantum Computing: does it work?

    Quantum computing holds the promise to change our lives by efficiently solving computing problems that are intractable today, such as simulation of quantum systems for synthesis of materials and drugs. A quantum computer comprises both a quantum processor and a classical electronic controller to operate and read out the quantum devices. The quantum processor must be cooled at cryogenic temperature in order to show quantum behavior, thus making it unfeasible to wire thousands of signals from the cryogenic quantum devices to a room-temperature controller.

    While this issue can be solved by placing also the electronic controller at cryogen¬ic temperature, which electronic technology is the best choice for its implementation? This talk will address the challenges of building such electronic controller, and answer whether a standard CMOS technology can be employed for the required analog and digital circuits operating at 4 K and below.

    Advanced Antenna Arrays for Modern Radar and Communication Systems

    Abstract: Several of today’s radar and wireless communication applications are shifting their operation to higher frequency to fulfil more demanding requirements on resolution, compactness and data rates. For this reason, there is a growing need to develop low-cost integrated circuit transceivers working at millimeter and sub-millimeter waves.

    However, on-chip antennas are currently characterized by very poor radiation efficiency and extremely narrow bandwidth. My approach of combining the concepts of connected arrays with artificial dielectrics will solve the inefficiency problem and enable high-efficiency on-chip antenna designs.

    Similar concepts can be also realized at microwave frequencies in printed circuit board, allowing for low-cost phased array antennas with state-of-the-art performance in terms of scan range, bandwidth and polarization purity.

  • Rob Remis
    Imaging with Waves

    We present an overview of our current wave field imaging and inversion research. Effective inversion strategies for important applications in Magnetic Resonance Imaging (MRI), nano-optics, and subsurface monitoring will be discussed. In particular, dielectric shimming (shaping of the radio frequency field in MRI) as well as inversion algorithms that determine the dielectric properties of various tissue types based on measured MRI data will be considered, and state-of-the-art model-order reduction techniques for large-scale wave propagation problems will be discussed as well.


    Inverse Problems in Electromangetics

    Challenges and New Frontiers

    IEEE AP-Sdistinguished Professor Andrea lecturer: MASSA
    University of Trento and Director Eledia Research Center

    Inverse problems arise when formulating and addressing many synthesis and sensing applications in modern electromagnetic engineering. Indeed, the objective of antenna design, microwave imaging, and radar remote sensing can be seen as that of retrieving a physical quantity (the shape of the radiating system, the dielectric profile of a device under test, the reflectivity of an area) starting from (either measured or “desired”) electromagnetic field data. Nevertheless, the solution of the well‐known theoretical features (including ill‐posedness, non‐uniqueness, ill‐conditioning, etc.) of electromagnetic inverse problems still represents a major challenge from the practical viewpoint. Indeed, developing and implementing robust, fast, effective, and general‐purpose techniques able to solve arbitrary electromagnetic inverse problem still represent a holy grail from the academic and industrial viewpoint. Accordingly, several ad‐hoc solutions (i.e., effective only for specific application domains) have been developed in the recent years

    In this framework, one of the most important research frontiers is the development of inversion techniques which enable the exploitation of both the information coming from the electromagnetic data and of that which is provided by prior knowledge of the scenario, application, or device of interest. Indeed, exploiting a‐priori information to regularize the problem formulation is known to be a key asset to reduce the drawbacks of inversion processes (i.e., the its ill‐posedness). However, properly introducing prior knowledge within an inversion technique is an extremely complex task, and suitable solutions are available only for specific classes of scenarios (e.g., comprising sparseness regularization terms).The aim of this talk is to provide a broad review of the current trends and objectives in the development of innovative inversion methodologies and algorithms. Towards this end, after a review of the literature on the topic, different classes of methodologies aimed at combining prior and acquired information (possibly in an iterative fashion) will be discussed, and guidelines on how to apply the arising strategies to different domains will be provided, along with numerical/experimental results. The open challenges and future trends of the research will be discussed as well

    Design of mm-wave, multifunction ICs for data communication and remote sensing

    Prof. Herbert Zirath
    Chalmers University of Technology

    FLYER OF THE SEMINAR___________
    The transmission rate of wireless data in the mobile networks is doubling every year due to the increased usage of mobile multimedia services like streaming video, music, television, data transfer in smartphones and laptop-computers etc. This tendency will require continuously improved telecom infrastructure regarding both base-stations and the backhaul communication links. Today, the E-band (71-76, 81-86, 92-95 GHz) is employed increasingly in the networks, allowing multi Gbps data rate. In a near future however, the E-band will be crowded, and novel, higher frequency bands will have to be employed as well. Several hundred Gigahertz bandwidth is available for new communication and sensing applications just waiting to be exploited at frequencies above 100 GHz. Until now, components for making such ‘THz-systems’ have been too expensive, too bulky, too power hungry and nonsufficient in terms of generating enough power for communication systems. With newly developed RFIC-processes, it is now possible to design multifunctional integrated circuits, realizing a full ‘frontend on a chip’ at frequencies well beyond 100 GHz. Recent results from ongoing projects aiming at enabling new applications for next generation mobile infrastructure, 5G, and security imaging, up to 340 GHz will be reported. So far, critical building blocks such as LNA, PA, VCO, modulator and demodulator, frequency multiplier, power detector and mixer have recently been developed, and results will be reported. Multifunction front-end circuits such as complete receive and transmit RFICs, mixed signal designs for co-integrated baseband/frontend ICs, and radiometer ICs have also been developed and will be reported as well, including the newly developed D-band (110 to 170 GHz) frontend chipset demonstrating state-of-the-art bitrate of beyond 40 Gbps.

An overview of my past and ongoing research activities will be also presented, with emphasis on novel solutions to improve power efficiency and spectral purity of RF/mm-wave transceivers.

    • Morteza Alavi: Universal Transmitters for 5G
      Today, our daily activities are intertwined with the Internet. The ever-growing demand to swiftly get access to the data-cloud systems leads to huge data traffic. In order to seamlessly transmit and receive these gigantic data, _ 40 GB, agile radio-frequency (RF) transceivers are inevitable.

      These radios must be capable of supporting the current and future communication standards such as 5th generation of wireless mobile communications. The ultimate goal is that they can be implemented as universal radios whose modes of operation can be defined by their clients. To address these demands, RF transmitters are currently reinvented and are directed towards digital-intensive architecture. In this short presentation, we will briefly describe the strengths,possibilities, and challenges that exist for these advanced transmitters. First and foremost, the concept of RF-DAC based transmitters will be introduced. Next, the talk will review various RF-DAC based transmitters that have already been implemented at ELCA. Eventually, the presentation will concisely unveil the future directions of the research of these software-defined transmitters at ELCA.

    • Faruk Uysal: Distributed Radar Networks: Beyond a single radar
      The number of operational radar is rapidly increasing due to the growing demand of the remote sensing. Software defined radio and emerging single-chip radar technology make use of radars in every aspect of life such as autonomous driving, safety and security applications. With the increase of active transmitters, spectrum management and coexistence started to become a concern for some radar systems. In this talk, the previous applications of waveform, frequency agility will be reviewed to bring multi-functionality to the modern radar system. Finally, we will discuss the future research for distributed radar networks and how to fuse data from various radars to acquire different aspects of a target to be viewed simultaneously.

    Wideband Integrated Lens Antennas for Terahertz Deep Space Investigation

    Ozan Yurduseven

    The Terahertz (THz) band is the portion of the spectrum that covers a frequency range from 300 GHz to 3 THz. The potential of this band has been proven for numerous type of applications including medical imaging, non-destructive testing, space observation, spectroscopy and security screening, thanks to its good compromise between the spatial resolution and penetration. Most of these applications demand for high spatial and range resolution of the images, as well as fast acquisition time. To fulfill such requirements, focal plane arrays (FPAs) need to comprise a large number of elements and be able to operate over broad bandwidths. Moreover, fabrication of the FPAs with thousands of antenna elements becomes a real issue at such frequencies due to the fabrications constraints and immense manufacturing costs

    Physical Foundations Underlying Green Information and Communication Technologies

    Earl McCune

    There are physical limitations on how much energy efficiency can be realized from any actual hardware used to implement any communications standard. Experience shows that in most instances the signals adopted by the standard committee place an additional ceiling on the achievable energy efficiency using that hardware. For example, there is hardware that is capable of providing more than 60% energy efficiency under ideal conditions, but for some standardized signals the maximum achievable efficiency drops to 7%. This drop in achievable efficiency is predictable, and such analyses should become part of standards committee deliberations. Such a low operating efficiency is not compatible with IoT, 5G, and other upcoming Standards objectives.

    This presentation was originally given to the IEEE Green-ICT Initiative Steering Committee at the IEEE Board meeting series in New Jersey on June 16, 2016. It establishes the reasons why such efficiency ceilings occur and shows how to predict them. Further, recipes are provided on how it is physically possible to simultaneously achieve high bandwidth efficiency and optimum energy efficiency along with the PSD impacts that come with these more Green-optimized signal modulations.

    Thesis Presentation

    Analysis and Design of Pulsed Photoconductive Antennas

    Siyi Zhou

    Photoconductive antennas (PCA) are widely used in contemporary THz systems, especially in terahertz time-domain spectroscopy. They are used to radiate and receive THz power. The study of the generation and reception of THz radiation involves both semiconductor theory, electromagnetics, and antenna theory. In this work, after a review of some equivalent circuits for analyzing PCAs, a novel Norton equivalent circuit model is discussed. It effectively describes the coupling between the photoconductor and the antenna. In order to increase the radiated THz power, a connected array solution of PCA is discussed. Connected arrays allow an efficient radiation of the antenna on a large bandwidth and are therefore suitable for radiating the picosecond pulses generated in the photoconductor. In order to realize a connected array of PCA, a proper biasing circuit has to be designed. Such circuit can involve the use of inductors manufactured in printed circuit board technology. Two possible designs of inductor are also discussed.

    During the Microelectronics Colloquium "Extreme Electronics". Three new Assistant Professors (Tenure Tracker) of the Microelectronics Department will present a lecture in this context.



    This will be a good occasion to meet the new staff members and learn about their research. There will be a drink afterwards as well.

    Vasiliki Giagka - Active Implantable Microsystems
    Implantable devices have been part of our lives for many decades now. The understanding of the electrical properties of the transmitted signals in our bodies have given researchers ideas on how to interface with them by using electronics. The concept of active implants refers to the miniaturisation of the electronics and their integration into microsystems suitable to live in our bodies. These devices can be employed to write signals to the body, inhibit undesired functionality for target organs, or read signals that convey the intention of our organism. This talk will focus on presenting some of the main applications and possibilities of active implants, and will discuss the challenges related to implantable microsystems, through the example of the design, fabrication and evaluation of a stimulating active electrode array for rehabilitation of walking after spinal cord injury

    Daniele Cavallo - Towards the implementation of Integrated,On Chip Terahertz Systems
    Terahertz (THz) sources and detectors have been developed in the last years for applications such as space observation, spectroscopy and security screening. However, until now, the components for making such THz systems have been very bulky and pricey, and thus not suitable for cost-driven commercial applications of THz technology. In the next years, my research will be focused on the development of low-cost, efficient and highly-integrated THz systems. On the one hand, the rapid scaling of CMOS and SiGe BiCMOS will eventually enable the realization of low-cost THz electronics. On the other hand, a careful co-design of the electronic circuit, the antenna and the quasi-optical system is crucial to bring real advances in this field. An overview on the ongoing research activities on integrated THz transceivers will be presented, with emphasis on novel solutions to improve the efficiency of on-chip antennas.

    Fabio Sebastiano - Cryogenic CMOS for Quantum Computers
    Quantum computers hold the promise to change our everyday lives in this century in the same radical way as the classical computer did in the last century, by efficiently solving problems that are intractable today, such as large number factorization and simulation of quantum systems. Quantum processors must be cooled at cryogenic temperatures well below 1 K and each of their quantum bits (qubit) must be controlled by a classical electronic interface. Since future quantum processors with practical applications will require up to thousands or millions of quantum bits (qubit), the electronic controller must operate at cryogenic temperatures as close as possible to the quantum processor, to avoid the unpractical requirement of thousands of cables from the cryogenic refrigerator to a room-temperature controller. This talk will address the challenges of building such a scalable silicon-based cryogenic electronic controller, focusing on to use standard CMOS technology to build complex analog and digital systems and circuits operating down to 4 K and below.

    Mm-Wave In-Package Antennas for Short-Range Car Radar Application

    Wenda Zhu


    The automotive radar market is rapidly expanding, with the need of including multiple sensors on board of vehicles to assist the drivers. Short-range radars have recently attracted great attention for applications ranging from parking assistance to collision avoidance and crash mitigation. These radar systems, operating at 77 GHz, have high potential to replace ultrasound sensors, which are mostly used nowadays.
    The key drive for the development of short-range radars is the reduction in area, cost and power for such systems. Therefore, a high-level of integration is required for the entire front end, with the goal of incorporating the antennas and the electronics in a single compact module. Novel packaging technologies such as embedded wafer level ball grid array (eWLB) have introduced new possibilities to integrate single antennas or antenna arrays in the package.
    The aim of this master thesis project is to demonstrate the feasibility of integrating single and multiple antennas in the eWLB package, to avoid the need of external printed circuit boards, with consequent reduction of costs and complexity. The antennas must operate in the frequency band from 76 to 81 GHz and maintain high-quality radiation patterns within a wide field of view, which is crucial for the envisaged application.
    Several solutions have been investigated and compared. A possible design of a system including a transmit and a receive array has been proposed and its performance has been assessed with the aid of electromagnetic simulations.

    SPACEKIDs, or how to use KIDs in SPACE

    Photon noise limited performance over an octave of bandwidth

    Juan Bueno
    Sron

    We present the development of background limited kinetic inductance detectors (KIDs) for sub-millimeter (sub-mm) astronomy applications. The sub-mm radiation is coupled to the KID via a leaky wave antenna covering the frequency range from 1.4 to 2.8THz. We have developed a hybrid niobium titanium nitride/aluminium (NbTiN/Al) KID, fabricated on a silicon (Si) substrate, in which the leaky wave antenna and absorbing section of the KID are fabricated on a suspended silicon nitride (SiN) membrane. The radiation is coupled to the leaky wave antenna with a Si lens placed on top of it at a distance of 3μm. The crucial result achieved in this development is the observation photon noise limited performance both in the phase and amplitude readout simultaneously, with a good optical efficiency at a frequency of 1.55THz. The Fourier Transform Spectroscopy (FTS) measurements show the broadband radiation coupling for an octave of bandwidth, and the beam pattern measurements at 1.55THz are in qualitative agreement with the simulated patterns. In summary, we have developed a new fabrication route that assures photon noise limited performance, and a scalable assembly method that provides the 3μm gap space between the antenna and the lens. These developments assure background limited performance with a broad frequency coupling over an octave of bandwidth for sub-mm radiation.

    On the Control of Surface Waves in Integrated Antenna: Analysis and Design Exploiting Artificial Dielectric Layers

    Waqas Syed

    In the design of planar antennas, good front-to-back radiation ratio can be achieved by loading the radiating element with an electrically thick and dense dielectric slab. However, this leads to significant coupling of power into surface wave modes, via those rays that are radiated by the antenna at angles greater than the critical angle, thus deteriorating the antenna radiation performances.

    In this dissertation, a planar methodology to solve the issue of surface waves is presented, which can be used to obtain simultaneously high radiation efficiency and good front-to- back radiation ratio. This consists in engineering anisotropic equivalent materials, referred to as artificial dielectric layers (ADL), and use them to enhance the performance of planar antennas. A practical planar realization of this concept can be achieved by embedding inside the host dielectric a periodic array of sub-wavelength square metal patches in a multilayer configuration. In this work, the main aspects pertaining to the theoretical development and the practical implementation of ADLs are investigated.

    Quasioptical Imaging Systems at THz Frequencies

    Beatriz Blázquez

    The Terahertz gap is the portion of the spectrum lying between 300 GHz and 3 THz. The initial development of Terahertz technology was driven by Space-based instruments for astrophysics, planetary, cometary and Earth science. However, in recent years, the interest of Terahertz science has been rapidly expanded due to the emergence of new applications as secure screening of concealed weapons for military and civil purposes, biological screening, medical imaging, industrial process control and communication technology, to mention some of them. A common characteristic of THz systems is that all of them use quasioptical elements to focus the beams and achieve sufficient signal-to-noise ratios.

    This doctoral thesis has focus on the analysis and development of quasioptical systems for two different types of THz applications: direct detection for space and heterodyne imaging for security. In the first part, THz absorbers-based detectors for space applications are studied. As this type of detectors can only be studied in reception, their analysis, when located under focusing systems, is usually done by full wave simulations under normal incidence illumination. This method does not describe well the actual coupling to the focusing element when the F/D ratio of the system is relatively small. A spectral model based on Fourier optics has been developed for an accurate and efficient analysis of linear absorbers under THz focusing systems for both small and large F/D ratios. The second part of this thesis is devoted to the optical system of a THz imaging radar for security screening. The goal in this part was to provide an existing THz imaging radar with new capabilities by using quasioptical solutions that do not modify the scanning mechanism and the back-end electronics. On one hand, the radar has been provided with an all quasioptical waveguide that performs time-delay multiplexing of the beams, reducing the image acquisition time a factor of two by only adding some extra optical elements to the system. Furthermore, the feasibility of this technique to be applied to large linear arrays of transceivers is proven. On the other hand, the radar was provided with refocusing capabilities by implementing the classical optical solution of translating the transceiver.

    Flat Optics

    Professor Stefano Maci
    Professor at the University of Siena (UNISI) and Director of UNISIs Ph.D. School of Information Engineering and Science

    Metasurfaces constitute a class of thin metamaterials used for controlling plane waves and surface wave. At microwave frequencies, they are constituted by sub-wavelength size patches printed on thin grounded dielectric substrates. By averaging the tangential fields, metasurfaces may be characterized by homogenised isotropic or anisotropic boundary conditions, which can be approximated through homogeneous equivalent impedances. In the low frequency regime and in absence of losses, this impedance supports the propagation of a surface wave. The impedance can be spatially modulated by locally changing the size/orientation of the printed elements. This allows for a deformation of the wavefront which addresses the local wavector along not-rectilinear paths. The ray paths are subjected to an eikonal equation analogue to the one for Geometrical Optics rays in graded index materials. For this reason we will refer to the theory which regulates the SW propagation as Flat Optics. In this presentation, we introduce the Flat Optics theory for surface waves for both isotropic and anisotropic MTS, deriving the basic relations between ray-paths, ray velocity and transport of energy for both isotropic and anisotropic boundary conditions. The relationship with Transformation Optics is discussed.


    CMOS and SiGe RFICs for Microwave and MM-Wave Phased Arrays

    Gabriel M. Rebeiz, University of California, San Diego

    This talk will present the latest work on microwave and mm-wave phased arrays and imaging systems at UCSD. The talk shows that one can build large phased arrays on a single chip covering distinct frequency bands, from 2 GHz to > 94 GHz, using commercial CMOS and SiGe processes. Typical designs include an 8-element 8-16 GHz SiGe phased array receiver, a 16-element Tx/Rx phased array at 42-48 GHz with 5-bit amplitude and phase control, and a 16-element Rx phased array at 77-84 GHz which includes a built-in-self-test system Also, an 8-20 GHz digital beam-former chip capable of multiple-beam operation and with high immunity to interferers will also be presented. IN terms of wafers-scale designs, 94 GHz and 110 GHz wafer-scale phased arrays will also be presented including high efficiency antennas. It will be shown that SiGe and CMOS has changed the way we think about phased arrays and imaging systems.

    Sensor management for surveillance and tracking. An operational perspective. March 5, 12.00 Aula, Senaatszaal. Promotor A. Yarovoy, co- promotor, H. Driessen

    Fotios Katsilieris

    Defence, March 5, 12.00 Aula, Senaatszaal. Sensor management for surveillance and tracking. An operational perspective. In the literature, several approaches to sensor (including radar) management can be found. These can be roughly grouped into: a) rule-based or heuristics; b) task-based; c) information-driven; and d) risk/threat-based. These approaches are compared in this dissertation and it is found that there is not a single approach that is both Bayes-optimal and takes into account explicitly the user requirements in different operational contexts. In order to overcome the challenges with the existing approaches, this dissertation proposes managing the uncertainty in higher-level quantities (as per the JDL model) that are directly of interest to an operator and directly related to the operational goal of a radar system. The proposed approach is motivated by the threat assessment process, which is an integral part of defence missions. Accordingly, a prominent example of a commonly used higher-level quantity is the threat-level of a target. The key advantage of the proposed approach is that it results in Bayes-optimal sensor control that also takes into account the operational context in a model-based manner. In other words: a) a radar operator can select the aspects of threat that are relevant to the operational context at hand; and b) external information about the arrival of targets and other scenario parameters can be included when defining the models used in the signal processing algorithms, leading to context-adaptive sensor management.

    The working mechanism of superconducting single photon detectors

    Presentation: Jelmer Renema, Huygens-Kamerlingh Onnes lab, Leiden, NL

    Superconducting single photon detectors (SSPDs) are of great technological importance, yet their working mechanism is still poorly understood. In this talk, I will present our results on this problem. I will show experimentally that a combination of a broad band of weakened superconductivity and the crossing of a vortex are responsible for the detection event. Furthermore, I will discuss the temperature dependence of the detection mechanism which is of great importance for applications.


    Kinetic Inductance Detectors: applications to millimeter Astronomy and Particle Physics

    Antonio DAddabbo
    Intstutut Nel (Grenoble).

    Kinetic Inductance Detectors (KID) have recently drawn the attention of the low-temperature detectors community. High sensitivity, low fabrication complexity, small time constant and most notably the intrinsic capability of frequency multiplexed readout open new possibilities for experiments which need large format arrays of ultra sensitive detectors. In millimeter Astronomy, the New IRAM KID Array (NIKA) instrument is today the most striking demonstration of this. It is a dual band hundreds-pixels KID based camera permanently installed at the focal plane of the IRAM 30-m telescope of Pico Veleta. Thanks to the NIKA observational campaigns, the NIKA collaboration could demonstrate performances comparable to the state-of-art of bolometers. The instrument is today open to the astronomers community. The will to extend KID technology to space mission demands a careful investigation of their interaction with the Cosmic Rays (CR). The understanding of the physics of high-energy interactions in the substrate of our arrays is crucial in order to optimize the KID performances in space environment. In the framework of the european SPACEKIDS project, this led us to implement a fully independent multiplexed readout system for the phonon-mediated particle detection with KID arrays. Moreover, using radioactive sources to simulate the primary CR hits, we studied the energy propagation induced by such interactions. The laboratory tests show promising results in damping the phonon propagation over distance and encourage deeper studies.


    Terahertz Sensing group seminar

    Group Meeting Presentation

    Ozan Yurduseven

    Dielectric lenses fed by wideband antenna feeds are widely used for the applications such as radio astronomy and space observation. For such applications, as a reflector feeder,it is often required to maintain the illumination of the reflector as constant as possible at all frequencies within the large band of operation. Reflector feeds that can operate with high aperture efficiency over wide frequency ranges have been previously developed for low-frequency radio telescopes. Some examples are the focal plane array of tapered slot antennas and the eleven antenna. However, there is currently a need for wideband reflector feeds also at much higher frequencies, for Terahertz (THz) and mm-wave space instruments.

    Another application for the dielectric lenses could be to use them directly as a THz imager with as many pixels as possible such that each pixel is associated to an independent beam generated by the lens antenna. In the scenario, it is very desirable to maintain the same field of coverage in order to avoid jiggling which decreases the imaging speed. To do so, it is required make a novel imager design that is able provide stable radiation patterns within the frequency band of operation.

    Distributed Power Absorbers under THz Focusing Systems

    Beatriz Blázquez

    Linearly polarized electromagnetic absorbers are often used in THz Space and Earth observation science as means of power detection. A promising use of these absorbers is in LEKIDs (Lumped Elements Kinetic Inductance Detectors). These detectors are absorber-based KIDs. In realistic scenarios, absorbers are hosted in the focal plane of focusing systems as it can be reflectors and lenses. An analytical spectral model able to accurately and efficiently characterize absorbers distributed in the focal plane of focusing THz systems is presented. The model is obtained by using a Fourier Optics representation of the electromagnetic field in the focal plane in conjunction with an equivalent network representation for the interaction of plane waves with distributed absorbers. The model has been validated by comparisons with numerical full-wave simulations, and used to design a few architectures based on lens coupled Kinetic Inductance Detectors, which show high absorption efficiency over a large bandwidth.

    Large format, background limited arrays of Kinetic Inductance Detectors for far-IR astronomy

    Jochem Baselmans

    The sub-mm wavelength band (from roughly 100 GHz to 10 THz) contains a large fraction of light emitted in the universe. However, observations are sparse, part due to the lack of good observation sites but especially due to the lack of available technology. Microwave Kinetic Inductance Detectors (MKIDs), proposed 10 years ago, could open up a new era in sub-mm astronomy as they allow 10-100x larger instruments than the present 1000 pixel class systems available. The goal of the Dutch MKID development is to reach the sensitivity only limited by the background radiation of the universe. This is called photon noise limited sensitivity (or BLIP). A part from photon noise, MKIDs also suffer from intrinsic noise, due to random generation and creation of excitations, but this contribution is small. In this presentation I will explain the need and status of sub-mm astronomy, explain the fundamental limits of MKIDs and explain the concept of photon noise limited radiation detection.

    Introduction to Asymptotic High Frequency Ray and Incremental Techniques for Modeling the Field Scattered by Electrically Large

    Giorgio Carluccio

    Modern applications of electromagnetic theory often require the prediction of wave propagation and diffraction in large complex environments. Typical examples of interest involve the performance prediction of antennas placed on aircrafts, naval platform, satellites, or the prediction of propagation of radiated fields from a base station to users in presence of large buildings as in the case of urban wireless communication, or in the presence of large mountains in a rural environment, etc. Another application of interest of electromagnetic theory is the calculation of the Radar Cross Section of objects that are large in terms of the wavelength (airplane, ships, etc.). Full wave numerical methods become intractable for solving such large problems. Conversely, asymptotic high frequency ray and incremental techniques are efficient for treating these kind of problems accurately. Furthermore, they also provide a simple physical picture of the radiation and diffraction mechanisms involved. An overview of asymptotic high frequency techniques and some relevant recent results will be presented.
