Evolutionary algorithm for bandstop Frequency Selective Surface

In recent years,there has been an increasing interest on the study of Frequency Selective Surfaces, thanks to their particular electromagnetic properties. One among their broad range of applications is band-stop spatial filter, which is constructed by periodic arrays of usually metallic elements on a dielectric substrate. This paper will present the effectiveness of an Evolutionary Algorithm, namely Meta-PSO, in optimizing multi-dimensional electromagnetic problem. All these concepts are integrated into a case study of dual rectangular ring loop-type frequency selective surface, printed on a FR4 substrate.
