Concluding remarks
This research examined the generation of tunable EM surface waves at magnetized plasma – graphene – magnetized plasma – PMC planar interfaces. We demonstrated that the propagation features associated with surface waves( i. e., effective mode index, propagation frequency, and phase velocity) are strongly dependent on magnetized plasma features( i. e., plasma frequency and cyclotron frequency) and graphene features. We also studied the propagation frequency of the proposed waveguide structure and found that propagation frequency fluctuations offer additional flexibility to modify its plasmonic properties. It is believed that the proposed scheme could provide a useful approach for the design of high-performance THz devices.
