The Design of Band-pass Frequency Selective Surface with the Grid Dielectric Metamaterial

摘要

Metallic parts are indispensable to traditional frequency selective surfaces. However, for millimeter waves, because of surface wave skin effect, the loss of metal-containing FSS is so large that the performance is badly affected. Besides, metal materials are quite unfavorable for high-temperature resistance and corrosion resistant requirements. The article adopt period dielectric structure to achieve band-pass frequency selective properties. The design principles proposed in this paper are of great practical values in designing all-dielectric metamaterials frequency selective surfaces.
