中文摘要	为了降低探测设备或制导武器对军事装备的威胁,研究了可见光、远红外与多种激光(0.93,1.06,10.6 m)兼容的隐身光子晶体薄膜的设计与优化问题。首先分析了已有的远红外与10.6 m激光兼容的隐身光子晶体的缺陷,主要是10.6 m激光的隐身性能随其入射角度增大而迅速降低;然后在保证远红外隐身性能的前提下,提出了通过展宽光子局域的方式来优化这一缺陷的思路。对于优化后的光子晶体薄膜,当入射角度在0°~60°内变化时,10.6 m处的反射率始终保持在20%以下,即提高了10.6 m激光隐身性能对入射角度的稳定性。在此结构的基础上,通过叠加准周期结构的方式来实现隐身波段向可见光与其他军用激光的拓展。得到的光子晶体薄膜具有黄、绿或蓝的特征,可以用来模拟荒漠、林地或海洋的颜色,并且其在0.93 m和1.06 m波长处的反射率随入射角度变化始终保持在10%以下,理论上可以大幅减小该激光的回波功率。
英文摘要	In this study, we design and optimize a new type of stealth photonic crystal film for visible-light, farinfrared, and multi-wavelength (i.e., 0.93, 1.06, and 10.6 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-m lasers; however, the stealth performance of the 10.6-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° to 60°, the reflectance of the optimized photonic crystal films remains less than 20% at 10.6 m, which improves the stealth performance stability of the 10.6-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 m and 1.06 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.
