The use of microcavity resonance mode to achieve the surface plasmon in the waveguide transmission control. Respectively changing the length of the groove, the distance between the two grooves and the dielectric constant of the filling material of the groove to achieve the specific filtering effect, and the electromagnetic induced transparency caused by the resonance of the surface plasmon in the waveguide is analyzed according to the electric field distribution, and the dynamic adjustable plasma Body-induced transparent effect device. The FEM is used to simulate the design.
