▎ 摘　　要

NOVELTY - The device has a wave absorbing unit provided with a bottom layer metal and wave absorbing sheets. Each of the wave absorbing sheets is adhered on the bottom layer metal. Each of the wave absorbing sheets is orderly formed with a graphene layer and a dielectric layer from up to down by attaching a top metal. The graphene layer of each wave absorbing sheet is respectively connected with the bottom layer metal through an independent power source, where cross-sectional area of each wave absorbing sheet is different. The wave absorbing sheet is formed as a square block. USE - Adjustable bandwidth and absorption frequency band graphene wave absorbing device. ADVANTAGE - The device regulates voltage exerted on the wave-absorbing sheet so as to adjust absorbing band of the absorbing sheet, so that the voltage can be applied to different absorbing sheets of different sizes, which can realize different absorbing bandwidth of each wave absorbing sheet on absorbing unit and improves the absorbing bandwidth by adjusting an absorption frequency band. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an adjustable bandwidth and absorption frequency band graphene wave absorbing method. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of an adjustable bandwidth and absorption frequency band graphene wave absorbing device.
