The design of multi-layered gangbuster periodic array for wide-band filter application

Abstract

The objective of this paper is to design a band-pass filter for wide-band application. Periodic array, frequency selective surfaces (FSS) with gangbuster elements is selected as optimization objective because of its good wide-band performance. The optimization algorithm, differential evolution strategy (DES) is employed to synthesis the configuration of FSS. The analysis of frequency response of FSS screen is solved by employing the spectral-domain method of moment (MoM) technique. The good stability of frequency response with respect to the incident angle is demonstrated.
