Proposing a dual-band metamaterial absorber designed for S and C band applications on a metal-backed dielectric substrate. The design incorporates square and circular split-ring geometries to induce absorption bands at 2.78 GHz and 5.78 GHz. Notably, the absorber showcases polarization insensitivity and robust stability against oblique electromagnetic wave incidence, bolstering its practical utility in wireless applications. Analysis of current distribution patterns and surface power loss density provides insights into the structural attributes. Moreover, the presence of a design parameter allows for tuning the resonance frequencies of the structure. The design boasts a high quality factor, which is essential for sensing applications. Finally, the proposed metamaterial absorber finds potential applications in sensors and electromagnetic detectors. |
