Abstract:An equivalent circuit model-based method for synthesizing wideband hand-stop frequency selective surface (FSS) has been proposed in this letter. Compared with previous works, the proposed method solves the problem of acquiring FSS structural parameters from the desired frequency response. In the proposed method, equivalent circuit parameters are first derived from the desired frequency response via the transmission line model, and then FSS structural parameters are determined from the equivalent circuit parameters with curve fitting technique. For verification, a dual-layer hand-stop FSS composed of square-loop arrays separated by dielectric substrate has been designed, fabricated, and measured. Simulation results show that the designed FSS can provide a stop hand operating at 13.5 Cu with a fractional bandwidth of 88.9%. Good agreements between the simulated and the measured results can be observed.
