%0 Journal Article %T A Single-Layer Meta-Atom Absorber %A Ihar Faniayeu %A Viktar Asadchy %A Tatsyana Dziarzhauskaya %A Igor Semchenko %A Sergei Khakhomov %J Physics %D 2014 %I arXiv %X We realized and experimentally tested a conceptually new kind of electrically thin absorbers of electromagnetic waves. The idea is to utilize a single layer of precisely designed meta-atoms. This allows one to design an absorber with unprecedentedly small thickness. The absorber implies absence of a ground plane. High efficiency of the realized structure in the S band is demonstrated. The conceptual idea of the proposed absorber can find many applications especially at optical frequencies. %U http://arxiv.org/abs/1404.1816v3
