Abstract

This disclosure relates generally to a composite reconfigurable intelligent surface system for real time beam steering and method thereof. Conventional method for real time beam steering includes bulky systems with several antenna elements and amplifiers to shape and control the beam. The present disclosure provides a composite reconfigurable intelligent surface (CRIS) for real time beam steering. The CRIS is formed from a set of constituent reflecting surfaces which in turn are generated from unit cells. These unit cells are responsible for providing individual phase reflection performance utilizing the installed varactor diode in each unit cell. The CRIS can provide a) multi-beam reflection performance, b) polarization sensitive operation, c) 2D beam steering abilities, d) real-time beam control, e) null point reduction for beam shaping requirements and f) dependable pattern stability over a suitable range of frequencies.
