ACKNOWLEDGEMENTS
The first person that I would like to thank is my wife Chiara Pelletti for supporting me with her love, for believing in me, and for walking next to me along these past three years.
Thanks also to my parents and to my brother Lorenzo who always helped me, telling me to never give up during hard times.
I would also like to thank Prof. Agostino Monorchio for giving me his
time, experience, help and for doing all it was possible for him to let me
grow with experiences abroad. Thanks to Prof. Raj Mittra, for his precious
and immeasurable mentoring, and who took care of me as soon as I arrived
in State College. During the years spent at the Electromagnetic
Communication Lab at Penn State University, he found himself in the
difficult task of growing me and guiding me in solving the electromagnetic
problems of and trying to pass me part of his endless knowledge. I would
like also to thank to Prof. Giuliano Manara for arranging this wonderful
group of persons working in the Microwave and Radiation Laboratory of
Pisa University.
