The Design of a Wideband Microwave Absorber Based on Resistively Single Square-Loop Arrays

Abstract:

A non-magnetic microwave absorber was proposed, for which the-10dB absorbing bandwidth would operate over all the X-band with a total thickness of 4 mm. The designed structure was composed by resistively single square-loop FSS on the surface of metal-backed dielectric substrate. The influence of the substrate and FSS was discussed for absorption optimization. Besides, the current distribution of the FSS was investigated to explain the principle of resonance. Good accordance of the experimental results and the simulated results has been achieved, indicating the feasibility of our designed structure and the reliability of the simulated method.
