Abstract

A compact Meta-surface absorber based on a novel combination of concentric split-ring resonators (SRRs) and arc dipoles is presented in this work. The proposed CSAD unit cell is a copper structure consisting of Quad dipoles and SRRs with a substrate with a dielectric constant of 4.3 and the tangent loss will be 0.02. The design resonates,17 GHz with a bandwidth of 300 MHz and 99.9% absorption. The symmetric single-band meta-surface allows for polarization-independent, angle-stable absorption up to 60°. The unit cell size for the proposed design is 10.375 × 10.375 × 1.6 mm³. It can be used for reducing the radar cross-section for stealth applications, such as UAVs that require selective frequency absorption. Simulations closely match observations, verifying the meta-surface's high stability and demonstrating its usefulness for practical electromagnetic validations.
