▎ 摘　　要

NOVELTY - Bi-directional absorbing electromagnetic shielding window comprises a first transparent absorption layer (3) that is sequentially stacked and arranged in parallel, transparent medium A (4), metal mesh A (5), transparent medium B (6), second transparent absorber layer (7), transparent medium C (8), metal mesh B (9), transparent medium D (10), and a third transparent absorption layer (11). USE - Bi-directional absorbing electromagnetic shielding window for multi-layer graphene grid/metal grid cascade structure (claimed). ADVANTAGE - The bi-directional absorbing electromagnetic shielding window has high electromagnetic shielding and high transmission. DETAILED DESCRIPTION - Bi-directional absorbing electromagnetic shielding window comprises a first transparent absorption layer that is sequentially stacked and arranged in parallel, transparent medium A, metal mesh A, transparent medium B (6), second transparent absorber layer, transparent medium C, metal mesh B, transparent medium D, and a third transparent absorption layer. The first and third transparent absorption layers comprise a graphene grid film which is separated by a transparent medium, and the second transparent absorption layer comprises 1-6 layers of graphite separated by a transparent medium and the metal mesh B, which are arranged in parallel to each other, and constitute a transparent reflective layer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the bi-directional absorbing electromagnetic shielding window for multi-layer graphene grid/metal grid cascade structure.
