An optimization approach based on the diffential evolution strategy (DES) is applied to the design of frequency‐selective surfaces (FSS). The spectral Galerkin method is used to analyze the electromagnetic scattering from a FSS screen while DES is used to tune the FSS unit‐cell dimensions and dielectric properties in order to achieve the prescribed frequency responses. The DES is compared to the real‐coded genetic algorithm. The simulated results of FSS dipole arrays are presented, which demonstrate that DES is a more simple, yet more efficient and more robust, method for the design of FSS. © 2005 Wiley Periodicals, Inc.
