▎ 摘　　要

NOVELTY - The device has a metal base plate (1) and a middle layer (2) that is provided with the metal base plate. The metal base plate and middle layer are provided in square shape, and whose length and width are same. The middle layer is set with round disc (6) that is provided with a graphene layer (3), a metal layer (4) and a polymer layer (5) from bottom to top. The material of metal base plate is gold. The material of middle layer is magnesium fluoride. The material of polymer layer is polyimide. The thickness of metal base plate is 100nm, and the thickness of middle layer is 20nm. USE - Adjustable infrared wave dual-band/triple-band graphene material absorbing device. ADVANTAGE - The electric tuning performance is improved. The joint debugging is achieved. The absorbing performance is stable. The absorbing device has simple structure and size of the absorbing device is reduced. The convenient manufacture of the absorbing device is achieved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an using method of adjustable infrared wave dual-band/triple-band graphene absorbing device. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of the absorbing device. Metal base plate (1) Middle layer (2) Graphene layer (3) Metal layer (4) Polymer layer (5) Round disc (6)
