摘要
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 tocomposite 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. Thephotonic crystal is designed and fabricated by applying electron beam evaporation and thin film deposition technolo-gy, which is stealth at 3~5 μm and compatible with laser waveband at 0.93 μm, 1.06 μm and 10.6 μm. It is very im-portant for aircraft nozzle position stealth. Spectrum analysis shows that the specifications meet application require-ments.
