Non-Foster Circuit Loaded Metasurface Reflector for Polarization Conversion

The present work explains possible implementation of non-foster circuit integrated planar metasurface reflectors for polarization conversion applications. The proposed active matching technique employed to control phase of reflection. This effectively helps maintaining impedance match for large size periodic reflectors made of smaller unit-cells. Here, a negative capacitance converter based NFC is proposed with a controllable phase to help polarization conversion behavior.
