超材料在军用隐身中的应用研究

Application research in metamaterials for military stealth

随着探测手段的发展,智能化与高精化的军用隐身探测技术对隐身材料的性能提出了更高的要求,传统材料受限于本身的性能很难实现轻量、宽频、强吸收等隐身要求,而超材料由于其可以按人的意志设计、调整结构并获得相关性能,在隐身领域具有极强的发展潜力,因此超材料在军用隐身领域中的相关研究受到了极大关注。本文综述了超材料的发展、特殊性能及应用,着重讨论了雷达隐身超材料、红外隐身超材料、雷达/红外兼容隐身超材料以及激光/红外兼容隐身超材料的研究与发展,指出目前超材料在军用隐身方面的研究多数停留在实验阶段,难以适应复杂多变的实际环境,今后应将研究集中在低成本制备与应用、宽频多波段兼容以及高耐温、高耐蚀性与高户外稳定性等方面。

With the development of detection methods,the intelligent and high-precision military stealth detection technology has put forward higher requirements for the performance of stealth materials,the traditional materials are limited by their own performance,and it is difficult to achieve stealth requirements such as lightweight,broadband,and strong absorption.However,the metamaterials have great potential for development in the field of stealth due to their ability to design,adjust structures,and achieve related performance according to human will.Therefore,the research on metamaterials in the field of military stealth has received great attention.The development,special properties and applications of metamaterials were reviewed in this paper,focusing on the research and development of radar stealth metamaterials,infrared stealth metamaterials,radar/infrared compatible stealth metamaterials,and laser/infrared compatible stealth metamaterials.Finally,it was pointed out that the research of metamaterials in the field of military stealth mostly stays in the experimental stage,and it is difficult to adapt to the complex and changeable practical environment for practical application,the research of metamaterials should be focused on low-cost preparation and application,broadband multi-band compatibility,as well as high temperature resistance,high corrosion resistance and high outdoor stability.
