Abstract
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 ( ω p ), cyclotron frequency ( ω c ), 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.
