Automatic design of inductive FSSs using the genetic algorithm and the MoM/BI-RME analysis

This paper describes an automatic procedure for the design of frequency selective surfaces (FSSs), consisting of thick metal screens periodically perforated with apertures. The optimization tool is based on the genetic algorithm and embeds a recently developed analysis method, named the MoM/BI-RME method. The optimization code selects the most suitable shape and dimensions of the aperture elements in order to satisfy the design specifications. An example reports the synthesis of a dual-band dual-polarization FSS.
