Abstract
This manuscript explores the plasmonic characteristics of monolayer graphene in anisotropic plasma dielectric planar structure. The complex conductivity of monolayer graphene is modeled by Kubo formulism. Due to anisotropy of plasma medium, higher and lower modes are demonstrated to explore the properties of proposed waveguide structure. Incident frequency-dependent both propagating modes are discussed for normalized phase constant as well as phase velocity under the different values of chemical potential, relaxation time, number of graphene layers, electron plasma frequency and cyclotron frequency. Field profiles for anisotropic dielectric are also presented to confirm electromagnetic surface waves condition. The presented results are being used to increase the efficiency of a graphene-based chip photonic system.
