EM performance analysis of multilayered metamaterial frequency selective surfaces

This paper presents EM performance analysis of the multilayered metamaterial FSS using TLTM method. It is shown that a multilayered metamaterial structure reveals the FSS properties. For efficacy of the method, the computed results are validated for metamaterial FSS structure such as tri-layer radome with the reported results in the open literature. Excellent matching is found between the computed and reported results. Further, a five-layer metamaterial FSS radome is investigated for TE and TM polarizations at incidence angles 0°, 30°, 45°, and 60°. It is observed that a multilayer metamaterial FSS radome exhibit multi resonance properties with proper tuning of thickness of the layers.
