Synthesizing Multiple Beams, Sum and Difference Beams at 28GHz Based on A Programmable Metasurface

Programmable metasurfaces (PMs) are consisted of reconfigurable digital elements, and electromagnetic properties of the PMs can be manipulated by configuring digital states of these elements. This paper proposes to synthesize multiple beams, sum and difference beams based on a PM. Theoretical calculations validate the functions of the presented PM.
