Design of an Isotropic Microwave Screen from Dipole Arrays using Genetic Algorithm

摘要

In this paper, we discuss the design of a multilayered Frequency Selective Surface (FSS) with low transmission coefficient, for two principal polarisations, via application of a genetic algorithm (GA). A very simple two-step approach is considered by first studying the scattering of a single dipole array in dielectric layers, then optimising a multiple FSS screen comprising several such dipole arrays. Numerical results are compared to the experimental data.
