NOVELTY - The utility model claims a strip and continuous layer graphene-based dual-band terahertz wave absorbing device, belonging to the technical field of terahertz wave absorbing device, using the graphene surface plasma characteristic, comprising a graphene strip (3), a continuous graphene layer (4) made of gold of the metal substrate (1), medium layer (2). The utility model mainly through finite element method calculating and simulating the graphene to absorption spectrum of the terahertz wave, the wave absorbing device structure optimization to obtain the dual-band high-efficiency of the terahertz wave.
