摘要：
A graphene-based terahertz tunable negative refractive index metasurface has been demonstrated. The proposed metasurface unit-cell comprises of a metallic fractal cross resonant ring and embedded graphene, which presents a dynamic negative refractive index in the corresponding bands by modulating the chemical potential of the embedded graphene.
