The Physics of Self-Complementary Metasurfaces Under Circularly Polarized Waves

Self-complementary metasurfaces illuminated with circular polarization are studied in this paper. Some general properties for the transmission and reflection coefficients are derived. Here a self-complementary metasurface composed of rectangular holes and rectangular patches was simulated to obtain the scattering parameters. This geometry may be used for conversion from circular to linear polarization with any polarization angle or broadband power dividing.
