▎ 摘 要
NOVELTY - The structure has a shielding optical window provided with a transparent absorption layer (3), two transparent units (4, 6) and two metal net grids (5, 7). The transparent absorption layer is provided with multiple layers that are separated from a graphene network gate film of one of the transparent units. The metal net grids are connected together to form a translucent reflective layer. A mesh cell opening area is formed on an array period unit. An outer side of the transparent absorption layer is fixed with a single-layer anti-reflection film (2) and a single-layer protective layer (1). USE - Strong electromagnetic shielding optical window graphene net gate and dual-layer metal net grid composite laminated structure. ADVANTAGE - The structure has high transmittance performance. The structure avoids high transmittance low electromagnetic reflection problem by using a transparent electromagnetic shielding process with strong electromagnetic shielding performance. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a strong electromagnetic shielding optical window graphene net gate and dual-layer metal net grid composite laminated structure.
