Switching Of Terahertz Plasmon Propagating Direction In A Dual Layer Graphene With Periodic Grating Gate
5TH INTERNATIONAL CONFERENCE ON METAMATERIALS AND NANOPHOTONICS (METANANO 2020)(2020)
Abstract
Switching of terahertz plasmon propagation direction in a periodic graphene structure with a double grating gate is studied theoretically. The coefficient of transformation of an incident electromagnetic wave into a propagating plasmon is numerically calculated. It is shown that near the "radiative" and "nonradiative" mode crosses plasmons propagating can be switched between forward and backward directions with respect to the x-axis by tuning voltage values applying to sub-grating gates. The absolute value of the transformation coefficient can exceed the unit value because of the gain provided by the active graphene.
