▎ 摘　　要

NOVELTY - The photonic crystal comprises multiple graphene pairs distributed at intervals. Multiple first dielectric layers (B) are located between adjacent graphene pairs. The graphene pairs are provided with two single-layer graphene (G) that are arranged parallel to each other. A second dielectric layer (C) is located between two single-layer graphenes. The thickness of the first dielectric layer is greater than the thickness of the second dielectric layer. The thickness of the first dielectric layer is less than the thickness of the second dielectric layer. USE - Photonic crystal based on graphene pair. ADVANTAGE - The crystal has a high light band resistance filtering function. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a photonic crystal. First dielectric layers (B) Dielectric layer (C) Single-layer graphene (G)
