▎ 摘　　要

NOVELTY - The method involves providing a meta metal, which is included in a graphene meta material, where the graphene meta material is provided for vertically combining the graphene and the meta material. The terahertz resonant frequency is provided, where the graphene meta material is irridiated. The metal gap sets are provided for diversifying a space angle between an asymmetry arc-shape metal pattern ring and a pumping light pulse wave. The graphene and the meta material are combined in the graphene meta material, where a terahertz wave is generated (S300). USE - Method for generating the terahertz wave. ADVANTAGE - The meta metal is included in a graphene meta material, where the graphene meta material is provided for vertically combining the graphene and the meta material, and hence ensures adjusting the intensity of the irradiated terahertz wave in an effective manner and controls the terahertz generation intensity, and also increases the terahertz domain resonance of the meta material. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of a pumping light pulse wave. (Drawing includes non-English language text).
