Abstract: In this letter, a novel design based on phase gradient metasurfaces (PGMs) is proposed to reduce the radar cross section (RCS) and enhance the gain of patch antennas. The PGM unit consists ...
Abstract: Since a typical intelligent reflecting surface (IRS) comprises a large number of passive reflecting elements, it is crucial to update the reflection coefficients using a fast optimization ...
