Description
Summary:This paper presents the realization of a multifunction anisotropic metasurface capable of operating as both a half-waveplate and a quarter-waveplate in the C, X, and Ku bands. The numerical and experimental results demonstrate the metasurface is able to convert linear and circular polarizations to their respective cross-polarizations, as well as achieve linear-to-circular and circular-to-linear polarization conversions in the microwave frequency regime. Notably, the metasurface maintains high conversion efficiencies for both half-wave and quarter-wave plate operations, even when subjected to variations in the incidence angle. The underlying physical mechanism is elucidated through the analysis of eigen values, surface current distribution and the retrieval of effective physical parameters. The proposed metasurface is useful for communication and polarization manipulation devices due to its simple construction, compact size, angular stability, and multi-functionality.
