Light plasmon coupling at magnetized plasma–graphene interface

In this manuscript, a theoretical investigation of SPPs generated at magnetized plasma–graphene interface is presented. To model graphene conductivity, Kubo formula is utilized, and impedance boundary conditions are applied to obtain dispersion relation. In the presence of strong anisotropy of the plasma medium, the behaviors of the lower and upper plasmon modes are demonstrated. By examining the dispersion relation, it has been shown that upper and lower modes strongly depend on graphene and plasma features. It has been shown that effective mode index and phase velocity of proposed structure can be tuned by tuning graphene and magnetized plasma features. The proposed model may be exploited for a variety of applications, including sensing and integrated plasmonic circuits in the THz spectrum.
