摘要
为了降低**装备被可见光、红外或激光探测器发现的概率, 研究了可见光、远红外与1.06 μm及10.6 μm激光兼容隐身光子晶体薄膜。基于光子晶体的“光子禁带”和“光子局域”的特性, 利用传输矩阵理论设计了3种不同颜色的隐身光子晶体薄膜, 然后利用真空电子束蒸发镀膜技术进行了制备, 最后利用相关仪器测试并得到了微观截面图、可见光照片、远红外热像图和反射光谱。结果显示, 3种薄膜微观层间结合致密, 膜厚符合理论设计。可见光波段具有青、黄或紫的特征颜色, 可以组合形成迷彩图案来分割可见光图像。远红外大气窗口(8~14 μm)内发射率小于0.3, 可以有效抑制远红外辐射。反射光谱中1.06 μm及10.6 μm处反射率分别为10%和40%左右, 能够有效减弱入射激光的回波功率。
Abstract
We studied a new type of stealth photonic crystal films compatible for visible, far infrared, 1.06 μm laser and 10.6 μm laser, for the purpose of minimizing the threats to important military targets from visible, infrared and laser detectors. In this paper, firstly, three kinds of compatible stealth photonic crystals with different colors were designed and simulated by transfer matrix method(TMM), and then fabricated by vacuum electron beam evaporation coating technique. Finally, we tested them by using relevant instruments and obtained scanning electron microscope(SEM) photos, visible photos, infrared thermogram and reflectance spectrogram. The result shows that the bonding between layers of films is compact and the thicknesses conform to the theoretical design. The prepared photonic crystal films possess optical characteristics of cyan, yellow or violet, which can be used to form camouflage patterns to segment visible images. In addition, the average emissivity in 8-14 μm far infrared atmospheric window is less than 0.3, which can effectively suppress far-infrared radiation. The reflectivity at wavelength of 1.06 μm and 10.6 μm keeps at about 10% and 40%, respectively, which will enormously reduce the reflected power of the incident lasers.
