Design and Simulation of a Polarization-Independent Switchable Metasurface Rasorber/Absorber

Abstract

In this paper, a resistive-ink based polarization-independent reconfigurable Metasurface that switches its operation between Rasorber and Absorber using a p-i-n diode has been proposed. When the p-i-n diode is in ON state the proposed design operates in absorption mode with an absorption band from 8.50 to 19.02 GHz whereas for OFF state it operates as rasorber, where it has a transmission window at 3.88 GHz with an existing absorption band. The proposed structure can efficiently reduce radar cross-section of the potential target while communicating with friendly radar at the same time and thus finds applicability in radar stealth application.
