▎ 摘　　要

NOVELTY - Electromagnetic shielding optical window comprises a bi-graphene absorption layer and a double layer metal grid structure, and further comprises a first transparent absorption layer (3), transparent medium A (4), metal mesh A (5), transparent medium B (6), second transparent absorption layer (7), transparent medium C (8), and metal mesh B (9) assembly structure, which are sequentially stacked and arranged in parallel. USE - Electromagnetic shielding optical window. ADVANTAGE - The electromagnetic shielding optical window has strong electromagnetic shielding, low electromagnetic reflection, and high light transmission performance. DETAILED DESCRIPTION - Electromagnetic shielding optical window comprises a bi-graphene absorption layer and a double layer metal grid structure, and further comprises a first transparent absorption layer, transparent medium A, metal mesh A, transparent medium B, second transparent absorption layer, transparent medium C, and metal mesh B assembly structure, which are sequentially stacked and arranged in parallel. The first transparent absorption layer absorption 1-6 layers of graphene film separated by a transparent medium, and the second transparent absorption layer comprises 1-3 layers of graphene film separated by a transparent medium. The metal grating A and the metal mesh B are arranged parallel to each other, and constitute a transparent reflective layer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the electromagnetic shielding optical window.
