US Patent 11024952 Broadband dual polarization active artificial magnetic conductor

A system and method for a dual-polarized active artificial magnetic conductor (AAMC) is presented in this disclosure. An embodiment of the proposed system comprises an array of unit cells that reflects electromagnetic waves polarized parallel to a surface with a zero-degree phase shift. The array of unit cells has impedance elements connected to neighboring impedance elements with non-Foster circuits coupled in a crossover configuration, each impedance element being coupled to a ground with a conductive via.
