A Metamaterial Based Microwave Absorber Composed of Coplanar Electric-Field-Coupled Resonator and Wire Array

In this paper, we present a new type of a double-negative metamaterial absorber (MMA) with a periodic array composed of in-plane an electric-fleld-coupled-LC (ELC) resonator and a wire. In contrast to common MMA conflgurations, a metallic pattern layer of the proposed absorber is placed parallel to the incident wave propagation direction. An appropriately designed combination structure is etched on one side of an FR-4 substrate. Here, we fabricated a prototype absorber with a planar array of 66 £ 30 unit cells. Our experiments showed that the proposed absorber exhibited a peak absorption rate greater than 86% at 10.1GHz irrespective of the incident angles up to 60 - .
