A Broadband Metamaterial Microwave Absorber Utilizing Both Magnetic and Electric Resonances

摘要

This paper introduces a thin wideband metamaterial microwave absorber. It employs both magnetic and electric resonances in the unit-cell design, and has a measured – 10dB absorption level from 6.52 GHz to 16.51 GHz, which agrees well with the simulation results. The relative bandwidth is 86.7%. The absorber maintains a −10dB absorption level from 6.80 GHz to 14.32 GHz within 30° TE mode incidence, and from 7.56 GHz to 16.97 GHz within 30° TM mode incidence.
