Application research in metamaterials for military stealth

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.
