A novel and polarization insensitive triband absorber using a non-uniform design approach on a flexible material for X-band applications
2026
Overview
To address the issue of satisfying absorption levels in the microwave X-band region, this study proposes a tri-band metasurface absorber that makes use of a new non-uniform technique. A unit cell is used to form the proposed absorber. This unit cell is printed on a jeans dielectric substrate, which has a dielectric constant of 2.2. copper material is chosen as a radiating patch for the proposed unit cell. The radiating patch contains different polygons with different sizes. The structure has been designed in four phases to have three absorption peaks. The structure that is being proposed is resonating at three different resonant frequencies, which are 9.98GHz, 10.43GHz, and 11.30GHz. Irrespective of polarization angles and mode of propagation, the structure produced absorptances as 95.1, 97.3, and 99.89, respectively for the corresponding resonant frequencies. The absorber that has been proposed possesses an electro-magnetic characteristic that is effective for microwave applications, particularly for satellite and radar telecommunications. Additionally, bending analysis confirms the robustness of the design under conformal conditions, making it suitable for practical X-band applications such as radar cross-section reduction, satellite communication systems and electromagnetic interference mitigation. This work contributes to SDG 9: United Nations Sustainable Development Goal 9 by advancing innovative, flexible electromagnetic absorber design for next-generation X-band applications.
