Abstract
This article reports on the study of a compact dual-band ultrathin polarization independent metamaterial absorber for C- and X-band applications. Designed absorber structure is composed of two different structural configurations labeled as Structure-A and Structure-B. The geometrical dimensions of both the resonators are optimized so that both can contribute one distinct absorption band with near unity absorption point. The electrical dimensions of the designed unit cell, corresponds to the first absorption peak of 4.95 GHz, is 0.11λ0 ×0.11λ0 ×0.009λ0. Since the geometry of designed absorber have four fold symmetry, hence it offers polarization independent behavior. Absorption mechanism and metamaterial characteristics of the designed absorber structure have been examined with the normalized input impedance and dispersion diagram respectively. Proposed absorber structure is designed and analyze using Ansys HFSS 14.0 3-D simulation software. © 2018 Electromagnetics Academy. All rights reserved.
