Andrea, who joined EEMCS a year and a half ago, is happy in his new environment. “My colleagues in the Microelectronics department are almost all IEEE-fellows”, he says admiringly. “I hope to follow in their footsteps.” He is an international expert on Terahertz (THz) antennas. On the electromagnetic spectrum THz is located between the upper end of the microwave range and the far infrared, a region that is almost entirely unexplored. “Broadband imaging, my specialty, is essentially not done”, says Andrea. “In my proposal I addressed one of the fundamental problems: dispersion. In order to radiate efficiently antennas have to be large. However, in large antennas the ‘phase centre’, the point from which the radiation spreads outward, moves according to frequency. I pioneered an antenna where it always remains in the same position. It’s a scientific breakthrough with applications ranging from deep space investigation and environmental monitoring, to security screening and biomedical imaging.”
