NOVELTY - A terahertz broadband absorption device. The utility model based on the graphene-constructing super-material terahertz broadband absorber, for theoretical analysis and simulation to terahertz wave broadband absorption body through time domain finite difference method, constructing the terahertz broadband absorption body unit structure is the three-layer structure of graphene-polymer-metal Au. When the graphene Fermi level is 0.5eV, the ultra-material absorber is too stable absorption of the terahertz wave at 0.9 in ultra-wide frequency range, frequency domain of 0.75~2.0THz The utility model has high absorption rate and the corresponding wide and meets the design intention.
