针对现代战争探测和精确制导系统由单一波段向复合波段扩展，对伪装材料提出了更高的要求。光子晶体作为一种人工晶体功能材料，利用其带隙特性实现在中红外波段的伪装，采用电子束蒸发和薄膜沉积等技术，设计并制备在3~5μm隐身同时兼容0.93μm，1.06μm和10.6μm激光波段的光子晶体。对飞行器尾喷管部位的隐身具有重要的意义。光谱分析表明，各项指标满足使用要求。

In modern war, the detection and precise guidance systems have been developed from single band to composite band, which put forward higher requirements on camouflage material. Photonic crystal as a kind of artifi?cial crystal function material, its band gap characteristics are used to realize camouflage at mid-infrared band. The photonic crystal is designed and fabricated by applying electron beam evaporation and thin film deposition technolo?gy, which is stealth at 3~5μm and compatible with laser waveband at 0.93μm, 1.06μm and 10.6μm. It is very im?portant for aircraft nozzle position stealth. Spectrum analysis shows that the specifications meet application require?ments.
