STUDY OF REFLECTION CHARACTERISTICS OF JERUSALEM AND GRIDDED JERUSALEM CROSS FREQUENCY SELECTIVE SURFACES

Abstract

Frequency Selective Surfaces (FSSs), which find wide spread applications as filters for microwaves, have been the subject of extensive studies in recent years. In the present study, reflection characteristics of Jerusalem cross and Gridded Jerusalem cross Frequency Selective Surfaces for TE, TM incidence at various angles were discussed. These Frequency Selective Surfaces are analysed by using Method of Moments (Mo M). The operator equation is formed using electric field boundary condition. This operator equation is converted into spectral domain using Floquet harmonics. This operator equation is converted into matrix equation by Galerkin's procedure. Roof-top functions are chosen as both basis and testing functions, computer simulations are carried on for calculating the reflection characteristics of Jerusalem cross and Gridded Jerusalem cross FSSs at various angles of incidence The results closely agrees with the predicted results.
