▎ 摘　　要

NOVELTY - The structure has a planar substrate whose surface is provided with multiple disks. A three-dimensional (3D) substrate annularly wraps the planar substrate. The disks are periodically arranged in a honeycomb shape to form a diamond-shaped crystal lattice. Each disk is filled with graphene, where lattice constant of a plasma photonic crystal is in a specific value. Distance between center of the disks satisfies a crystal lattice period. The substrate is made of silicon di-oxide material and graphene plasma. USE - Plasma photonic crystal structure. ADVANTAGE - The structure improves light wave transmission performance, reduces the transmission loss, adopts a stable crystal structure by dynamically adjusting the chemical potential of the graphene disk, maintains the boundary transmission state of the topology protection on the graphene surface, and dynamically adjusts uniform structure of the plasma photonic crystal structure. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a plasma photonic crystal structure.
