摘要

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.
