▎ 摘　　要

NOVELTY - The composite structure comprises two graphene single layers respectively deposited on two sides of a non-eosin dielectric thin layer (G) to form a three-layer structure. A light wave passes through a certain graphene single layer at a non-vertical incidence angle to improve reflectivity of a resonance state, and obtain large Goos-Hansen displacement near the resonance state when the light wave passes through a certain graphene single layer at a non-vertical incidence angle. The graphene single layer is provided with a graphene layer (G-1) and a graphene layer (G-2). USE - Composite structure of a dielectric thin layer and graphene. ADVANTAGE - The composite structure improves reflectivity of a resonance state and obtain large Goos-Hansen displacement near a resonance state. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of a composite structure.
