All dielectric metamaterial frequency selective surface based on Y shaped barium strontium titanate ceramic resonator

摘要

In this paper, all dielectric metamaterial frequency selective surface based on Y shaped barium strontium titanate ceramic resonator is proposed. The simulation results show the bandwidth of the frequency selective surface can reach 2GHz, and the angle stability of the TE and TM mode is well. By introducing a Y shaped cavity into the ceramic resonator, the transmission characteristic curve of the frequency selective surface achieves two stop bands with bandwidths of 4.56GHz and 0.68GHz respectively and a pass band with a bandwidth of 0.28GHz. When the incident angle changes to 75°, a pass band with a bandwidth of 1.8GHz will appear for the TM mode. These results demonstrate that the proposed structure is an excellent candidate of all dielectric metamaterial and broadband frequency selective surface for high power microwaves.
