Frequency selective polarization conversion metasurface using E-shaped high permittivity ceramics

In this paper, a frequency selective polarization conversion metasurface is designed based on E-shaped high permittivity ceramics. A frequency selective polarization conversion is realized in 10.95GHz∼12.069GHz. Two magnetic resonances are generated, which lead to the cross-polarization reflection. The simulated results show that the maximum conversion efficiency is nearly 100% at the two resonant frequencies. In this paper, high permittivity ceramic material is used to design all-dielectric metasurface in microwave band. As an alternative method to design frequency selective polarization conversion metasurface, high permittivity ceramics provide potential applications in high temperature or high power.
