### PART 2: Assignment (1 EC)

Choose an assignment related to your specialization.## Study Goals

After the course the student will be able to:- Visualize the relationship between the scalar quantities used in Electrical Engineering, voltages and currents, and the corresponding vector field quantities, electric and magnetic fields.
- Qualitatively understand the properties of the lumped component circuit elements models which are valid at low frequency, based on their intuitive visualization of quasi static E.M. quasi static fields.
- Understand the fundamental mechanisms associated to losses in modern circuit designs: eddy currents, skin effect, mismatch and radiation
- Quantify the properties, propagation constants and characteristic impedances, of circuits which depend on their length in terms of the investigated wavelength.
- Qualitatively understand the radiation properties of circuits, and the mutual coupling between antennas or circuits
