Graphene-based Metasurfaces for Multimode Tunable Terahertz Modulators

Not Accessible

Your library or personal account may give you access

Abstract

We present a hybrid graphene metasurface and its modulation by electrostatically tuning the conductivity of the graphene. Through modification of unit cell symmetry, multiple Fano-like resonances arise for additional modes over a 300 GHz range.
