Abstract
A reconfigurable intelligent surface is disclosed. The reconfigurable intelligent surface includes a switch layer that can transition to a metallic state from an insulator state and to the insulator state from the metallic state based on its temperature. A voltage is applied to the switch layer to control the temperature and control the state of the switch layer. Controlling the state of the switch layer allows the reconfigurable intelligent surface to operate in a transmission mode when the switch layer is in the insulator state and a reflection mode when the switch layer is in the metallic state.
