Design and Analysis of a 6G Low-loss Metamaterial Circular Polarizor

A 6G trilayers metamaterial polarization converter is designed and analyzed, we mainly focus on the analyze of the air Fabry-Perot Cavity is which act as interlayer, it efficiently enhance phase modulation effect and lower the insert loss. IL(Insert loss) is less than 1dB, PD(Phase Delay) is less than 90°±10°, AR(axial ratio) is less than 1.5dB, azimuth is less than 5°. As for multi-layer coupling analysis, we use brick-layer model and Fabry-Perot-Interference model to how can interlayer coupling enhance the phase and amplitude modulation.
