Abstract In this article, an analytical model is proposed for the study of Transverse-electric (TE) surface plasmon polaritons (SPPs) in nonlinear multi-layer graphene-based waveguides. Each graphene sheet has been located between two different Kerr-type layers. As special cases of the general, proposed structure, two new nonlinear graphene-based waveguides are introduced and investigated in this paper. The obtained results show that the propagation properties of these exemplary structures are adjustable via chemical potential and nonlinear coefficients. A large value of the effective index, i.e. neff= 82 is obtained for the chemical potential of 0.15 eV and the nonlinear ratio of 0.8 for the second structure at the frequency of 61 THz. The presented study suggests a novel platform in graphene plasmonics, which can be used for the design of innovative THz devices.

Plasmon Polaritons

The theoretical analysis of surface plasmon polaritons in magnetized plasma film walled by two graphene layers is presented in this manuscript. The conductivity of graphene is calculated from the Kubo's formula. By tailoring the graphene conductivity, the propagation of Surface Plasmon Polariton wave can be controlled. Under the certain boundary conditions Maxwell's Equations in differential form are used to solve the problem. For using these wave guides we also investigate factor of confinement and comparatively length of shorter propagation for parallel plate waveguide. The effects of chemical potential (μ), plasma frequency (ωp), cyclotron frequency (ωc), relaxation time (τ), and number of layers of graphene (N) on the dispersion curve are investigated. The present work may have potential applications in nano-waveguide designing and plasma optics technology in the gigahertz frequency range.
