Abstract
In this paper, a dual-band metamaterial absorber (MMA) ring with a mirror reflexed C-shape is introduced for X and Ku band sensing applications. The proposed metamaterial consists of two square ring resonators and a mirror reflexed C-shape, which reveals two distinctive absorption bands in the electromagnetic wave spectrum. The mechanism of the two-band absorber particularly demonstrates two resonance frequencies and absorption was analyzed using a quasi-TEM field distribution. The absorption can be tunable by changing the size of the metallic ring in the frequency spectrum. Design and analysis of the proposed meta-absorber was performed using the finite-integration technique (FIT)-based CST microwave studio simulation software. Two specific absorption peaks value of 99.6% and 99.14% are achieved at 13.78 GHz and 15.3 GHz, respectively. The absorption results have been measured and compared with computational results. The proposed dual-band absorber has potential applications in sensing techniques for satellite communication and radar systems.

Summary
Periodic arrangement of metallic patterns in the microwave frequency range using thin wires and certain design characteristics show unconventional properties of materials like negative values of permittivity, permeability, refractive index, etc. These characteristics-based materials are known as metamaterials and cannot be found in Nature. A significant number of researchers have been comprehensively studying these phenomena during the last few years observing such characteristics of metamaterials. A detailed review on photonic, terahertz and microwave applications was provided in [5], where the authors cited numerous mechanisms as well as materials regarding metamaterial and metadevice research. Robust analysis and sophisticated design for sensing based on the metamaterial concept was described in [6,7,8], such as nanoparticles-inspired structural properties analysis in terms of Maxwell’s equation and their application in sensing, structures with near-zero parameters (like permittivity, permeability or refractive index) working principle with application potentiality, the substantial role of grapheme in the inhomogeneous spatiality, and non-uniform conductivity pattern in transformation optics, etc
