Abstract ■

In this paper we investigate how one can take additional advantage of coupled metal graphene plasmons. The dispersion relation for coupled metal graphene plasmons is presented here for a proposed multilayer structure. Graphene and couple metal graphene modes supported by this structure are shown below, these modes can depend very strongly on Fermi energy level values in the graphene layer at the sub-THz frequency range, which eventually can be used in a wide range of applications.
