An electrically controlled metaswitch is demonstrated by integrating passive metamaterial (metallic-slot array) with well-established nonvolatile flash memory technology [floating-gate (FG) structure]. In this hybrid configuration, the metamaterial acts as its control-gate layer while a monolayer gr...
