NOVELTY - The utility model claims a terahertz frequency range for applied to the graphene super-surface, the graphene surface graphene reflecting unit of number of units is composed of Nasterisk N, each graphene reflecting unit form a cuboid structure composed of a three-layer structure, the quartz medium plate each graphene reflecting unit comprises the upper layer of the graphene sheet, the middle layer and the metal floor of the bottom layer. the graphene sheet is set on the upper surface of the quartz medium plate, and the rotating angle of the graphene sheet is set on surface of the quartz medium plate is theta , the rotation angle theta is in the range of 90 to -90 any angle; the metal board is arranged on the lower surface of the quartz medium plate, the central point position of the graphene sheet central point position of the quartz medium plate. The utility model claims a graphene surface used in the terahertz frequency range can realize self-swirling wave of 0~360 degrees full phase modulation, the phase of the generated scroll wave more accurately so as to improve the performance of the vortex wave.
