X-Band Metamaterial Wideband Polarization Insensitive Thin Absorber using Lumped Resistors

Abstract

A novel frequency selective surface (FSS) based absorber with broadband characteristics is presented in this paper. The absorber is designed for X band applications. The absorber presented here is thin broadband and polarization insensitive owing to its four fold symmetric nature. The simple design of the structure makes it more realizable and hence practically feasible.
