Practical Perfect Absorption in Monolayer Graphene by Prism Coupling

Practical Perfect Absorption in Monolayer Graphene by Prism Coupling

We propose a practical perfect absorber comprising three dielectric layers for prism coupling with monolayer graphene embedded in the middle layer. Since the loss rate can be controlled by the graphene position within the middle layer, the limitation on the material index choice is greatly relieved,...

The proposed structure can adopt a thin layer of any absorbing material for perfect absorption owing to the adaptive loss rate feature.https://ieeexplore.ieee.org/document/8049443/Perfect absorbergraphenetotal internal reflection.
