A compact dual frequency absorber based on frequency selective surface

This article proposes a compact dual-band frequency selective surface absorber with dual frequency suppression features, the pattern of one cycle of the frequency selective surface is similar to that of "S". The parameters of the surface element are described in detail, and The transmission properties of the surface components were investigated using the equivalent circuit method. The proposed design also tests the stable response of incidence angle variations to TE/TM polarisation patterns.. The simulation results and the measured results are verified again by experiments. Finally, a novel frequency selective surface element structure is provided, which can be effectively applied to antenna stealth.
