▎ 摘　　要

NOVELTY - The structure has a main body provided with an electrolyte graphene sandwich layer (1), an isolation layer (2), a metal frequency selective surface layer (3), a medium layer (4) and a metal base plate (5). The electrolyte graphene sandwich layer is provided with a first graphene layer, an electrolyte layer and a second graphene layer. The electrolyte layer is formed between the first graphene layer and the second graphene layer, where the first graphene layer and the second graphene layer are single-layer graphene that is coated on PVC material film substrate. USE - Graphene and frequency selective surface based ultra-thin absorbing surface structure for use in communication, household consumer electronic and military stealth field. ADVANTAGE - The structure is simple in design and convenient to integrate, and has better practicability, and can dynamically adjust device reflection coefficient to realize wave and reflecting working state under effect of an external voltage. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a graphene and frequency selective surface based ultra-thin absorbing surface structure.
