基于光子晶体的中红外与多波段激光兼容伪装材料
Compatible Mid-infrared and Multi-band Laser Camouflage Material Based on Photonic Crystal
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3~5 μm隐身同时兼容0.93 μm, 1.06 μm和10.6 μm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。
Abstract
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 artificial 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 technology, 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 important for aircraft nozzle position stealth. Spectrum analysis shows that the specifications meet application requirements.
