▎ 摘　　要

NOVELTY - The window glass has a vacuum layer (3) provided between the outer glass (1) and the inner glass (2). The outer surface of the outer glass is provided with a microwave frequency selective surface structure array (11). The inner surface of the outer glass is provided with a microwave resonance absorption structure array (12). The inner surface of the inner glass is provided with an electromagnetic reflection film (13). The microwave frequency selective surface structure array is a pattern structure array formed by depositing a first transparent conductive film material on the outer surface of the outer glass. USE - Infrared and radar compatible invisible window glass with sound insulation and heat insulation function for military target in military reconnaissance. ADVANTAGE - The window glass integrates a transparent support structure and a compatible stealth function, and can realize broad-spectrum and high-efficiency microwave absorption and low infrared emissivity based on itself, the microwave absorption range can cover 520 GHz, and the absorption efficiency is greater than 0.9. The infrared emissivity of the glass surface is as low as 0.23, which can significantly reduce the heat radiation of the target, thereby reducing the probability of detection. The visible light transmittance of the window glass is above 60%. The window glass has the ability of sound insulation, noise reduction and heat insulation based on the vacuum spacer layer in the structure. The vacuum layer or air layer in window structure can reduce heat transfer, prevent internal and external heat exchange, and has certain heat insulation effect. The inner layer glass can effectively attenuate or reflect the electromagnetic wave radiation of the electronic component in the cabin to realize the efficient absorption of the external radar wave. The vacuum layer reduces the heat conduction of the window glass, which has heat insulation capability. The vacuum layer has sound insulation and noise reduction capabilities.
