▎ 摘  要

In this paper, a tunable electromagnetically induced transparency (EIT) structure using coupling hybrid graphenenanostrip is proposed. The structure comprises of a vertical graphene strip (VGS) and a pair of horizontal graphene strips (HGSs), the horizontal graphene strips placed alternately on both sides of vertical graphene strip. The EIT-like effect could be turned by changing the Fermi level of graphene instead of refabricating the geometrical parameter of structure, and the significant merits of proposed structure is distinct EIT-like effect could be observed in two perpendicular polarization directions, the influence of electron mobility on transparency windows is also analyzed. This work demonstrate a novel EIT-like phenomenon based on metamaterial and opens a new perspective in EIT effect applications.
