▎ 摘  要

An active electromagnetically induced transparency (EIT) analog adopting graphene as microstructure of metamaterial is investigated. The analog consist interconnected graphene strip (GS) and graphene split ring resonator (GSRR), which can act as bright and dark elements alternately. The distinct EIT-like effect can be generated by bright-dark mode coupling inxandypolarization directions. Further investigations reveal that EIT peak can be actively controlled via Fermi level of graphene, and theoretical analysis based on two particles mode express the reason. Moreover, notable EIT-like effect can also be generated in a wide range of polarization angles, and impact of polarization angle on EIT peak is also discussed in detail. These characteristic paves the way for the applications of EIT-like in sensor device.
