MG - Series Wire Mesh Shielding Glass

The conductive shielding layer of Aerobon's MG series shielding glass is the wire mesh film with high light transmittance. The wire mesh is made with special techniques and materials, and has a large visible area and good transmittance. Its special coating can realize the low reflectivity; with the perfect fitting between the excellent optical cement and glass, it can not only have favorable electromagnetic shielding effectiveness, but also has as high as 86% light transmittance.
Besides the fitting of a double-layer structure, such wire mesh film can also be closely stuck to the single-glass base material to form a special single-layer structure, which can effectively reduce the thickness of the shielding glass to 1.1mm; such product is very suitable for the optical shielding of a light and thin structure. The base material can also be selected flexibly. Both float glass base material and organic glass base material can be used in the single-layer and double-layer structure.

Analysis of the Shielding Property of MGWire Mesh Shielding Glass

SE=A+R+B+K1+K2+K3
SE: shielding property, A: absorption loss; R: reflection loss; B: multilateral absorption loss; Kl: correction coefficient of mesh number; K2: correction coefficient of low frequency transmittance; K3: intercoupling correction coefficient of nearby mesh holes
A: The bigger the linear diameter and the more the mesh number is, the better the absorption loss is. R: Relating to the conductivity and permeability of the wire mesh
B: neglectable when A>10dB; K1: the smaller the mesh surface area, the better the effect
K2: when the skin depth is near the mesh spacing, the shielding effectiveness will decline, which is particularly serious at a low frequency.
K3: When the meshes are closer to each other and the hole size is much bigger than the wire mesh diameter, there will be coupling between adjacent meshes to improve the shielding effectiveness.
