Frequency selective surfaces as spatial filters: Fundamentals, analysis and applications

In the present scenario, there are prime challenges that need to be addressed in modern wireless communication systems. These consist of implementation techniques which meant for increasing capacity and enhancing data rate providing better quality service. Frequency Selective Surfaces (FSSs) help address these by offering spatial filtering this paper, a detailed survey on FSSs is presented with focus fundamental principles, geometries, fabrication employed manufacturing. An extensive review understanding journey from traditional elements utilized making structures up three-dimensional FSS geometries. addition shapes structures, has also been design analysis geometries numerous applications. inherent property their capability act as filters when substituted electromagnetic radiation environment. Also, mechanism exhibited reported indicating differentiation basis applications frequency ranges surfaces exposed.
