Esclusioni: 02KSI; 01MPU 
Obiettivi dell'insegnamento
This course deals with the radiation of electromagnetic wave, and gives the bases to understand and analyze the phenomena of free propagation and radiation of electromagnetic waves. After having solved the radiation problem, the most simple antenna systems and components of microwave communication systems are analyzed.

Competenze attese
After completion of the course, the student will be able to analyze plane electromagnetic waves, simple radiation problems and radiating structures described in the course.

Prerequisiti
Electromagnetic Fields and Waves I, and all courses of Mathematics, Physics, Fundamentals of Electric Circuits, and relevant prerequisites.

Programma
Wave propagation and radiation. Plane wave propagation, polarization of electromagnetic fields. Stratified dielectric structures, planar waveguide, general concepts of optical fibers and dielectric waveguides. Solution of non homogeneous Maxwell equations: transfer function in spectral domain. Green's function as pulse response of the electromagnetic system. Solution in space domain with convolution integral. Equivalence theorem. Reciprocity theorem, Antennas and definition of their characteristic parameters: gain, directivity, effective area, EIRP, radiation impedance. Friis transmission equation. Radar equation. Wire antennas, aperture antennas, reflectors. Arrays.
