Electromagnetic induced transparency (EIT) in terahertz band can achieve group delay and transparent window, which is attractive in biosensing field. In this paper, based on the phase transition properties of vanadium dioxide (VO2), an EIT with metasurface is designed to adjust the frequency position of transparent window. The unit cell of the metasurface consists of a cut wire (CW) resonator embedded with VO2 and two C-shaped ring resonators. The simulations show that when VO2 is in the insulating phase, the EIT window appears at 0.58-0.74 THz. While VO2 is in the metallic phase, the EIT window is located at 0.37-0.50 THz. The proposed structure has the active regulation of the EIT frequency band, which provides great potential for the sensitivity detection in THz.
