Abstract:

Hybridization of fundamental and higher plasmonic modes of a graphene square screened by a metal back gate with the Fabry-Pérot resonances in barrier layer is predicted. We show that the absorption cross-section of higher plasmon modes in a screened graphene square is greater than that in the unscreened structure by an order of magnitude.
