Graphene-based Perfect Absorbers: Systematic Design and High Tunability

Research output: Chapter in Book/Report/Conference proceedingConference contributionScientificpeer-review

Abstract

Experimental realization of efficient graphene-based absorbers is a challenging task due to the low carrier mobility in processed graphene. In this paper, we circumvent this problem by placing uniform graphene sheets on metallic metasurfaces designed for improving the absorption properties of low-mobility graphene. Complete absorption can be achieved for different frequencies with the proper metasurface design. In the THz band, we observe strong tunability of the absorption frequencies and magnitudes when modulating graphene Fermi level.
