Tunable properties of graphene loaded waveguide surrounded by magnetic materials

Theoretically analysis has been accomplished for the propagating electromagnetic surface waves (EMSWs) at planar ferrite-graphene-ferrite waveguide structure. The characteristics curves are analyzed for the normalized phase and attenuation phase constant against the operating frequency. The impact of different parameters of ferrite and graphene are observed on the normalize phase and attenuation phase constant. In response to these parameters the structured waveguide exhibits the convenient propagation of electromagnetic surface waves with minimal propagation loss in the terahertz frequency region. The proposed waveguide avails position in nanophotonic devices, terahertz filters, highly integrated terahertz devices and communication systems.
