The transmittance property and steady-state magnetic field distribution of the sliver circular gap embedded with a sliver nanorod are investigated using the finite-difference time-domain method. Since the titled nanorod breaks the symmetric steady-state magnetic field distribution, Fano resonance occurs in the composite system. In addition, the transmittance spectrum depends strongly on the tilting angle and topologic shape of the nanorod. These results would be useful for designing filter for specific usage.
