In this study, Particle Swarm Optimization is applied for the design of Square Loop Frequency Selective Surfaces (the conventional Square Loop, Gridded Square Loop, and Double Square Loop) via their equivalent circuits. For this purpose, first the derivation of the equivalent circuit formulation is revisited. Then an objective function, which is based on the transmission coefficients at various frequencies at the pass/stop-bands, is defined. By means of an ANSI C++ implementation, a platform independent console application (which depends on the Equivalent Circuit Models and continuous form of Particle Swarm Optimization) is developed. The obtained results are compared to those in the literature. It is observed that the Particle Swarm Optimization is perfectly suitable for this sort of problems, and the solution accuracy is limited to and dominated by that of the Equivalent Circuit Model.
