Design and Analysis of Frequency Selective Surface at Ka/K/Ku Band

Abstract

In this paper we will give a new way to designing spatial filters (frequency selective surfaces) being widely used in several microwave and optical systems. In this paper we will analyze transmission and reflection of electromagnetic waves from complex thick/thin metallic frequency selective surface (FSS).In this work, we have designed the spatial filter (FSS) to be used in microwave/satellite communication. We have tried to overcome the limitations in form of accuracy and computational effort. Using CST software, the results for full wave analysis method are being evaluated.
