Band Stop Frequency Selective Surface Design Based on Equivalent Circuit

This paper presents a band-stop frequency selective surface (FSS) design method based on equivalent circuit. This method first constructs a band-stop filter circuit that meets the design goals, and then extracts the corresponding equivalent circuit parameters for rough FSS design. Finally, the original FSS structure is optimized by the full wave method to achieve the design goal. The article gives examples of single stop band FSS and dual stop band FSS, which proves that the method is simple and effective.
