A tunable Fano-like resonance in the hybrid construction between graphene nanorings and graphene grating is proposed. The simulation results reveal that the Fano-like resonance is generated between two bright modes, which are different from the previous studies of coupling between the plasmonics bright and dark modes. The adjustability of this Fano resonance is simply researched by changing the geometry parameters of the composite structure and the Fermi-energy of graphene. Also, the dual-Fano resonance can be realized by only decreasing the thickness of the substrate spacer without employing extra resonance mode.
