An Experimental Validation of Reconfigurable Intelligent Surfaces Achieving Pulse-Width-Modulated Singular Reflection Angles Without External Power Sources

Abstract: In this study, we introduce a design concept that leverages pulse width variation to enable a reconfigurable intelligent surface (RIS) and to autonomously switch reflection properties ...
