英文摘要	In this study, we design and optimize a new type of stealth photonic crystal film for visible-light, far-infrared, and multi-wavelength (i. e. , 0.93, 1.06, and 10.6 mu m) lasers respectively, to minimize the threats to important military targets from detection equipment and guided weapons. We first analyze the shortcomings of the existing compatible stealth photonic crystal films for far-infrared and 10.6-mu m lasers; however, the stealth performance of the 10.6-mu m laser rapidly decreases with increasing incident angle. We propose to address this problem by broadening photon localization while ensuring the stealth performance of far-infrared lasers. Therefore, when the incident angle varies from 0 degrees to 60 degrees, the reflectance of the optimized photonic crystal films remains less than 20% at 10.6 mu m, which improves the stealth performance stability of the 10.6-mu m laser. Further, we expand the stealth bandwidth of the photonic crystal films with respect to visible and other military-sensitive lasers by superimposing quasi-periodic structures into the films. The optimized photonic crystal films exhibit optical characteristics of yellow, green, or blue, which can be used to simulate the color of desert, woodland, or ocean regions, respectively. The reflectance at wavelengths of 0.93 mu m and 1.06 mu m is observed to be less than 10% with changing incident angle, which, in theory, will significantly reduce the reflected power of the incident lasers.
