▎ 摘　　要

NOVELTY - The device has a transparent absorption layers (3, 9) separated by a transparent medium (4) of a graphene mesh barrier film. A first metal mesh bar (5) and a second metal mesh bar (7) are arranged in a parallel manner to form a translucent reflective layer. The graphene mesh barrier film is formed on a mesh array structure. A mesh unit is formed with a square-shaped hole or a circular-shaped hole and a mesh unit opening area. Array period ratio of the mesh unit opening area is about 1. An anti-reflection film (2) is formed on a single-layer or multi-layer protective layer (1). USE - Dual-way grid/absorbing effect graphene dual-layer wire grid transparent electromagnetic shielding device. ADVANTAGE - The device has high electromagnetic shielding efficiency and high transmission rate, and can reduce problems of bidirectional low electromagnetic reflection. DETAILED DESCRIPTION - The mesh array structure is a two-dimensional array structure unit. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a dual-way grid/absorbing effect graphene dual-layer wire grid transparent electromagnetic shielding device.
