The tunable plasmonic-induced transparency (PIT) is proposed numerically in the plasmonic system composed of dual unsymmetrical resonators shaped metal-insulator-metal (MIM) waveguide. The specific filtering effects are realized by changing the length of the groove and dielectric constant. The phenomena of the plasmonicinduced transparency caused by the surface plasmonic resonance in the waveguide are analyzed according to the electric field distributions. The finite element method (FEM) method is conducted to verify numerical simulation. The structure is applied widely in optical communication, integrated optics, and lithography.
