Abstract: This invention is the Optically Powered and Controlled Non-Foster Circuit (OPCNFC) that is electrically floating; i.e., it does not have any metallic electrical/conductive connection to a power supply, ground, or control signal. Rather power and control signals are applied to the OPCNFC using optical energy. The Non-Foster Circuit (NFC) synthesizes negative inductance, negative capacitance, and/or negative resistance between metallic patches disposed in an array of an Artificial Impedance Surface (AIS).
