Paper Abstract

In order to realize the laser and thermal infrared compatible stealth, a photonic crystal (PC) stealth film for 1064nm laser and mid-and-far infrared is designed by using the heterostructure method and characteristic matrix method. The results show that the reflectivity of this PC film at the wavelength of 1064nm is as low as 1%, meaning that it can reduce the reflectivity echo of 1064nm laser. In the meantime, the reflectivity of this PC film in 3-5μm and 8-14μm wavebands is 94.3% and 84.1% respectively, allowing the PC film to suppress the thermal radiation of the heat source. Furthermore, the impact of the incident angle on the reflectivity of the PC film is very small, whether in 1064nm wavelength or mid-and-far infrared wavebands. Therefore, this PC film can realize the compatible stealth of 1064nm laser and thermal infrared.
