An Ultra-Wideband Polarization Conversion Metasurface with High Angular Stability

In this paper, a wideband polarization conversion metasurface with high angular stability is demonstrated by simulation. The angular stability is improved by loading the wide-angle matching layer and the metal column. Simulation results show that the proposed metasurface can convert linearly polarized incident waves into cross-polarized incident waves in a wide band of 6.4-17.6GHz (93.3%) with an angular stability of 67°. The metasurface has the characteristics of high angular stability and ultra-wideband, so it can be used in a wider range of electromagnetic fields.
