Polarization Angle Independent Metamaterial Absorber in both of C- and X-Bands

In this study, perfect metamaterial absorbers (MAs) based on circle- and square-shaped configurations that are numerically and experimentally designed and analyzed in both of C- and X-band. The proposed models have very simple designs and present perfect absorption for all polarization angles. A sensor application of the suggested model (for circle-shaped) is also presented to introduce further feature of the structure. Moreover, the suggested models can be easily reconfigured for THz and infrared frequency regimes to enable myriad potential applications such as sensors, defense systems and stealth in the next studies.
