The designed MMA structure consists of a resonator layer, dielectric layer, and ground plane. The resonator layer comprises three closed rings. The structure has been designed and analyzed using Ansys HFSS full-wave electromagnetic (EM) simulation software. The reported percentage of absorptions are 99.79%, 98.84%, 99.86%, and 98.98% at 2.01 GHz, 3.51 GHz, 7.26 GHz, and 9.41 GHz, respectively.eninfo:eu-repo/semantics/closedAccessConference Object10.1109/Metamaterials62190.2024.107032352-s2.0-85207847986
