Polarization and Beam Regulation of Electromagnetic Wave Based on Metasurface

The C-shaped split ring structure is applied in this paper to construct unit cells to convert linearly polarization signal into cross-polarization signal with high reflection efficiency. By reasonably designing phase-gradient between adjacent unit cells, the metasurface can realize beam control at 15 GHz. Simulation results have well confirmed that normally incident plane wave is reflected by 30° and 41°, which are in good agreement with the generalized Snell’s law.
