In developing our design for an ultra-thin metamaterial absorber tailored to X-band applications, we opted for a straightforward approach. The design incorporates a single sheet of metal, dielectric, metal on a glass epoxy/FR-4 substrate, showcasing remarkable performance. With absorptivity consistently surpassing > 85% across the entire X-band spectrum (8.0 GHz–12.0 GHz) and 99%, 99.6%, and 97.2% absorption observed at three different frequencies of 8.4, 10.25, and 11.6 GHz. Absorptivity also investigated for polarization angles ranging 0°–90° for TE-polarization. We delved into the absorption mechanism, explaining it through surface and electric current variation, hold up by constitutive electromagnetic parameters influenced by magnetic resonance. This design, marked by its low-profile and incident angle sensitivity, underscores its practical feasibility, positioning it as a better solution for applications in the X-band.
