The projects in this theme 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: micro-lenses excited by leaky waves with seamless integration in silicon technology. This antenna enables the fabrication of large flies eye cameras in just two wafers, and promises one order of magnitude better scanning performances than previous solutions.
Regarding theory, an analytical model to investigate the electromagnetic response of coherent THz arrays is the enabling tool for optimizing the camera performances. We 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.
