摘要：

In this paper, both linear cross-polarization conversion (CPC) and linear-to-circular or circular-to -linear polarization conversion based on a single reflective anisotropic metasurface are realized and experimentally demonstrated. The multifunctional CPC metasurface in the frequency range of 5.9-6.4 GHz and 8.7-17.7 GHz has a fractional band of 68.2%, and the efficiency reaches almost 100% under plasma resonance. In addition, the metasurface acts as a high efficiency circular-polarizer in the range of 6.7-8.4 GHz. Moreover, the polarization transforming functionality of the structure is stable for the change of incident angle for both x-polarized or transverse-electric (TE) and y-polarized or transverse-magnetic (TM) illumination up to 45 degrees. It can be seen that the anticipated hypersurface has potential applications in reflector antenna, satellite communication and radar.(c) 2023 Elsevier B.V. All rights reserved.
