Design of single layer wave-absorbers based on lefthanded materials

Abstract

A physical model of microwave-absorber with an air/left-handed material/metal structure is proposed, the absorbing characteristics of it is theoretically analyzed, the design fundamentals, ensuring that the absorber has a high absorbing performance in a certain frequency band, and the laws of the distributions of the electromagnetic parameters values satisfying the fundamentals are derived. The results of this work may be a reference to the designs of single layer wave-absorbers made of left-handed materials.
