| 摘 要： | 光子晶体的禁带特性为伪装材料的光谱控制研究提供了一条新的技术途径。利用传输矩阵的方法建立了一维光子晶体光谱透射、反射的理论模型，针对伪装材料近红外高反射、中远红外低发射的要求，优选Ag，MgF2和ZnS等材料作为光子晶体的薄膜材料，采用真空蒸发镀膜的方法制备出Ag/MgF2,Ag/MgF2/ZnS 4种不同周期结构的一维光子晶体，并实验研究了一维光子晶体的光谱反射和透过特性。结果表明:材料和周期结构对一维光子晶体光谱特性有不同的影响，通过优化设计可以实现在伪装波段内的光谱特性要求。

| Abstract: | The forbidden band characteristics of photonic crystal provide a new technology for the study of spectral control of camouflage materials. This paper built the spectral transmi-ssion and reflection theoretical model of one-dimensional photonic crystal with transmission matrix. Aiming at the demand of high reflection in near infrared and low emission in middle-far infrared wavebands of camouflage materials, Ag, MgF2 and ZnS were optimized as thin-film materials of photonic crystal, and by the way of vacuum evaporation filming, Ag/MgF2, Ag/MgF2/ZnS 1-D photonic crystals with different periodical structures were prepared. Spectral reflection and transmission characteristics of these 1-D photonic crystals were studied experimentally. Experimental results show that the materials and periodical structures influence the spectral characteristics of 1-D photonic crystals and by optimum design the photonic crystal can realize the spectral characteristics in camouflage waveband. |
