A tunable hybrid metamaterial in THz band has been designed and simulated. The resonance frequencies shift of this hybrid structure is obtained by actively varying the effective length of electrically resonant cross. This was realized by using Vanadium dioxide( VO 2) film bridges that can be triggered the insulator-metal phase transition at the four tops of the cross structure. Simulation results present that dual band resonances come from the individual structure. So this hybrid metamaterial based on VO 2 phase transition shows some advantages such as tunability,frequency agility,easily fabrication and polarization independency in THz band.
