摘要
采用传输矩阵法和蒸发镀膜工艺,设计并制备了一种中、远红外双波段兼容隐身的光子晶体薄膜。测量了该光子晶体膜层的实际厚度和中、远红外光谱反射率,所得结果与理论设计相吻合。研究结果表明,与红外隐身涂层和常规迷彩布两种传统红外隐身材料相比,光子晶体薄膜在中、远红外双波段抑制红外辐射的能力最强;室外环境辐照对光子晶体薄膜在8~14 μm及3~5 μm波段隐身效果的影响较小。
Abstract
A kind of photonic crystal (PC) film, which is compatible stealth in middle and far infrared bands, is designed and prepared based on the transfer matrix method and the evaporation film technology. The practical thicknesses and the middle and far infrared spectral characteristics of this kind of PC thin film are measured, which are in a good agreement with the theoretical design values. The results show that, compared with two kinds of conventional infrared stealthy material as the infrared stealth coatings and the conventional camouflage fabrics, the PC film has the strongest ability to suppress infrared radiation at both middle and far infrared bands. The influences of outdoor environment irradiation on the stealth effects of PC film at the bands of 8-14 μm and 3-5 μm are relatively weak.
