摘要

This article presents a novel X-shaped modified split-ring resonator (MSRR) broadband microwave metamaterial absorber for covert applications in the C, X, and Ku bands. The absorber features a 0.035-mm-thick annealed copper layer with X-shaped resonators on a 1.6-mm-thick FR4 dielectric substrate, with a unit cell of 0.254λ × 0.254λ at 7.64 GHz. CST Microwave Studio simulations show absorption peaks at 7.64 GHz (98.4%), 8.41 GHz (97%), 11.4 GHz (99.2%), and 12.66 GHz (99%). Parametric analyses are employed to optimize these frequencies using E-field, H-field, and surface current distributions. The design achieves high absorption for transverse electric (TE) and transverse magnetic (TM) polarization across incidence angles up to 30°, ideal for electromagnetic interference (EMI) shielding and stealth in military contexts.
