Dispersion Characteristics of Graphene Surface Plasmon Four Layers Waveguide

Abstract

A four layer waveguide has been introduced. Graphene layer is separate by metamaterial layer (MTM) from a plasmonic layer The dispersion characteristics of the propagation of TM surface Plasmon through the waveguide structure containing a graphene have been derived. We numerically analyse the propagation of surface plasmon at different waveguide parameters. The obtained results presents that we can control the propagation of the plasom as we changes the thickness of the MTM layer, the MTM parameters, and the graphened conductivity.
