▎ 摘　　要

Plasmonic metamaterial based on the graphene complementary split ring resonators is introduced and investigated. The underlying mechanisms of the resonances are explored in detail when such metamaterial is illuminated by horizontal and vertical polarization infrared lights, which provides us with a better understanding of the phenomenon of spectral responses. With its more pronounced spectral response and a tunability that is more conveniently recognized, such a metamaterial has great prospects for being adopted for practical applications in the future.
