Abstract:	A compact metasurface absorber based on a novel combination of concentric split-ring resonators (SRRs) and arc dipoles is presented in this work. The proposed CSAD-based absorber with a copper structure consists of quad dipoles and SRRs with a dielectric constant of 4.3 and loss tangent of 0.02. The design resonates near the frequency of 17 GHz with a bandwidth of 300 MHz and 99.9% absorption. The symmetric single-band metasurface 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 metasurface’s high stability and demonstrating its usefulness for practical electromagnetic validations. [ABSTRACT FROM AUTHOR]
