Electromagnetic Shielding Light Window with Double Graphene Absorber Layer and Double-layer Metal Grid Structure

Abstract

An electromagnetic shielding optical window possessing dual graphene absorption layers and a dual-layer metal mesh structure belongs to the optical transparent member electromagnetic shielding technology field and is formed by assembling a first transparent absorption layer, a transparent medium A, a metal mesh A, a transparent medium B, a second transparent absorption layer, a transparent medium C and a metal mesh B which are orderly laminated and parallelly configured. The first transparent absorption layers is composed of 1-6 layers of graphene mesh films separated by transparent mediums, the second transparent absorption layers is composed of 1-3 layers of graphene mesh films separated by transparent mediums, and the metal meshes A and B form a transparent reflection layer. The electromagnetic shielding optical window of the present invention solves the problem that a conventional transparent electromagnetic shielding technology can not consider the low-electromagnetic reflection, the strong electromagnetic shielding and the high light transmission simultaneously, and has the characteristics of high light transmission performance, strong electromagnetic shielding and low electromagnetic reflection.

Description

technical field [0001] The invention belongs to the field of electromagnetic shielding of optical transparent parts, in particular to an electromagnetic shielding light window with double graphene absorbing layers and a double-layer metal grid structure. Background technique [0002] With the development of radio, television, wireless communication technology and microwave technology, a large number of radio frequency devices are equipped in various places of human activities, and the spectrum range continues to widen, and the intensity doubles, which not only interferes with electronic equipment, but also affects human health. threaten. This invisible and intangible "electromagnetic pollution" directly acts on machines or human bodies, and is a serious "invisible killer". It has become the fifth largest pollution after air pollution, water pollution, solid waste pollution and noise pollution. Electromagnetic shielding (including absorption and reflection) is the main measu...
