A novel frequency selective surface with controllable bandwidth and steep rejection skirt

Abstract

A novel FSS has been presented that exhibits high selectivity of response compared with conventional FSS structures. The new FSS offers very good control of bandwidth, and yet it is based on a simple geometry that is easy to fabricate. Two design examples have been presented to demonstrate the concept. The structure has been analyzed using the full-wave mode-matching method and our results are in an excellent agreement with those obtained by CST MWS.
