Theoretical T Circuit Modeling of Graphene-Based Metamaterial Broadband Absorber
Source abstract
Abstract
We demonstrate a broadband light absorber with its absorption being able to reach as high as 90 % and above ranging from the ultraviolet to the visible regimes. A theoretical model is given for the purpose of analyzing the physical mechanism of the absorption. By applying the equivalent T circuit model of metamaterial layers to the analysis of our designed absorber, our calculated results are in good agreement to that of the theoretical model and satisfy the perfect-absorption condition very well.
