With graphene emerging as one of the promising materials in exploring novel and reconfigurable electromagnetic devices, in this paper, we summarize and discuss the electromagnetic property of graphene in different frequencies, as well as introduced two kinds of, namely, surface-wave and spatial-wave based electromagnetic devices base on graphene. Simultaneously, typical mechanisms for designing these...
Two dimensional graphene metasurfaces working in terahertz regime are proposed to realize dynamical control of wavefront with high efficiency. Each graphene metasurface consists of an array of graphene rectangle patches on square grounded dielectric substrate. The reflection amplitude and phase of graphene rectangle patches are investigated with different patch lengths and widths. It is found that...
