Summary:
FSS(Frequency Selective Surface) is composed of metal patches arranged at narrow intervals, and has the frequency-band-rejection and the frequency-band-pass characteristics[1]. On the other hand, AMC(Artificial magnetic conductor) is one of artifical materials, and has the PMC(Perfect Magnetic Conductor) characteristics in any frequency band. On the PMC surface, the high-frequency current isn't propagating. In addition, electromagnetic wave is reflected at the surface without phase rotation[2][3]. This paper describes the reflection and transmission characteristics of a double-layered FSS and its equivalent structure with the ground plane, and also discusses the relation between the filtering characteristics of a double-layered FSS and the PMC characteristics of the equivalent structure with the ground plane.
