摘要：
In this work, a T-shaped and square-liked ring resonator Metamaterial absorber has been presented. The unit cell consists components based on three hexagonal closed rings. Excellent absorption has been resulted by modifying hexagonal cell. The absorption rates are 95, 97 and 99% at 5.8, 9.52 and 11.97 GHz, respectively. The structure has been implemented on 1 mm-thick FR4 substrate considering low cost and simple process in fabrication. Results show wide-angle stability under TE and TM polarizations. The numerical simulation agrees the corresponding measurement.
