Abstract

The invention discloses an adjustable infrared camouflage and stealth thin film based on a phase change material, and the thin film comprises a zone control electrode which is located at the bottommost layer and is used for controlling the phase state of the phase change material in different zones of the thin film; a first photonic crystal layer, arranged at the upper part of the partition control electrode and used for realizing radiance regulation and control of a wave band of 8-14 microns; a second photonic crystal layer, arranged on the first photonic crystal layer and used for realizing radiance regulation and control of a wave band of 3-5 microns; and a metasurface radiation layer, arranged on the second photonic crystal layer and used for realizing high radiance of a wave band of 5-8 microns so as to dissipate heat of an object in a non-infrared atmospheric window. According to the stealth thin film, the phase state of the phase change material can be controlled through the subarea control electrodes, then the infrared radiation capacity of the thin film can be regulated and controlled in real time, and the stealth thin film has the opening / closing capacity for the stealth effect of an object, can be controlled in a subarea mode and has the capacity for disguising the infrared imaging characteristic of the object.

Description

technical field [0001] This application relates to the field of infrared stealth, in particular to an infrared camouflage and stealth film based on phase change materials. Background technique [0002] With the increasing improvement of infrared detection technology and electronic information processing system, technologies such as infrared detection, infrared night vision, and infrared guidance are more and more widely used in the military field, resulting in unprecedented huge threats to the survival of military equipment and combat personnel. test. Infrared detection technology can effectively improve the detection and identification capabilities of targets, and can overcome the impact of adverse weather conditions, low visibility and other factors on target reconnaissance. In order to avoid the detection of infrared detectors and improve the survivability of weapons and combat personnel, infrared stealth technology has become a research direction that has attracted much...
