Beam reconfigurable reflective metasurface for indoor wireless communications

Abstract

A reflective metasurface with reconfigurable beam is proposed for indoor wireless communications. It consists of 8 × 8 unit cells with tunable capacitors. By varying the capacitances, the reflective phase across the metasurface can be designed to facilitate different reflective angles for an incident wave. The simulation results show that the proposed reflective metasurface can deflect the incoming wave from the broadside by up to 47 degrees, with the maximum side lobe level of -11dB. The proposed design is envisioned for mitigating the problem of blind spots in indoor wireless communications.
