Dimensionally Adjustable Metamaterial Signal Absorber Design for Microwave S-Band Applications

Abstract

– In this study, the signal absorption of metamaterials was discussed and for this aim, a design capable of perfect signal absorption was realized. The suggested structure consists of a copper resonator on the front surface of the dielectric material and completely copper on the back surface. Accordingly, the suggested design was designed with a finite integration technique (FIT) based simulation program and numerical results were obtained. According to the results obtained from the suggested absorber design, the metamaterial absorber is able to absorb the incoming signal at a rate of 99.88% at a frequency of 3.2091 GHz. In addition, the suggested absorber design can be adjusted parametrically, and the absorption frequency and high absorption rate can also be adjusted in the microwave S-band (2–4 GHz).
