Estructura Metamaterial Quiral de tipo Fishnet con refracción negativa y bajas perdidas

Abstract

In this work the authors present a novel chiral metamaterial structure focused on providing negative refractive index and low losses in a wide frequency band. This new structure is constituted by the combination of two low losses structures, a composite chiral metamaterial and a modified fishnet structure. With the aid of a commercial electromagnetic software simulator, the structure is numerically analyzed and characterized. This new fishnet-like chiral metamaterial features two wide frequency bands wherein the refractive indices are negative and exhibits lower losses than its constituents do.
