Abstract
In the paper, we propose a multi-functional microwave device to realize the polarization conversion of transport waves based on the anisotropic metasurface which is composed of a series of flower-liked unit cells separated by air space. The simulation results show that the metasurface would convert the polarization state of the incident electromagnetic wave to the cross-polarization state in the frequency region of 7.2~8.8 GHz and the linear polarization (LP) state to circular polarization (CP) state from 8.8 GHz to 11.1 GHz. The conversion efficiency of cross-polarization conversion (CPC) for LP wave is larger than 0.9 even for the incident angle of 85°, except for the narrower bandwidth. While the LP incident can efficiently convert to CP transmission wave for incident angle below 60°. The outstanding angular stability is originated from the symmetrical configuration of the designed unit cell. Additionally, the influences of structural parameters on the polarization conversion are studied in detail.
