We report a 0.74-THz beam-steering and forming antenna based on dynamically reconfigurable photo-induced Fresnel zone plates (PI-FZPs) formed by patterned illumination of a high-resistivity silicon wafer using a digital light processing (DLP) projector. This approach eliminates the need for fabrication of circuits or devices on the semiconductor wafer. Using computer-generated PI-FZPs, the beam from...
A novel approach to reduce the dual band microstrip antenna Radar Cross Section (RCS) based on Artificial Magnetic Conductors (AMC) is presented in this paper, and making the size of the antenna which works at 5.1 GHz and 7.4 GHz decreases by 47%. The approach taken is to devise a new dual band AMC structure which has the same frequency with this antenna and load on both sides of the radiating patch...
