NOVELTY - The terahertz adjustable harmonic device based on graphene. The utility model relates to one kind of terahertz adjustable harmonic device based on graphene . The utility model is new type is for solving existing terahertz metamaterial tuner exist tuning frequency single tuning depth is small and problem. A based on graphene and a terahertz adjustable harmonic device of substrate, insulation medium layer and opening resonance ring structure layer composed of graphene, the substrate level set lower at most, the insulation medium layer parallel set up on upper surface of substrate, the opening resonance ring structure graphene parallel set with insulation medium layer on the upper surface of the middle position. The utility model is new type used for terahertz communication field.
