"The overall contribution of the research presented in this dissertation is to introduce a novel method for generating a reconfigurable reflectarray that is based on the creation of photoinduced plasma inside the semiconductor. An optically controlled variable slot located on the ground plane of a reflectarray antenna is utilized in the suggested scheme to change the distribution of phase on the surface of the reflectarray. This property can be used for dynamic beam scanning and beam shaping"--Abstract, page i. Photoconductivity. Beam optics. Microwave antennas Design and construction.
