摘　　要：现代探测系统由单一工作模式到复合工作模式的转变,对低目标特征材料的光谱特性提出了某些特殊要求。在文章中,基于一维掺杂光子晶体,设计了一种新型红外低目标特征材料,并研究了其复合结构对反射光谱的影响。发现在一定条件下,可以在反射光谱中的一个宽的高反射率波段内形成局部的狭窄低反射率区,从而为新型红外功能材料的研制提供了参考。As the working mode of modem detecting system is changing from single mode to compound one, materials with certain spectral characteristics are required to meet low observable demands. In the present paper, the authors designed a novel material with low target features in infrared band based on one dimensional doped photonic crystal, and investigated the influence of the composite structure on reflection spectrum. It was found that under certain conditions, a local narrow low-reflectivity region can be formed within a wide high-reflectivity band in reflection spectrum, providing a reference for the development of a new type of infrared functional materials.
