my country’s stealth metamaterial technology has reached the international leading level, and Kuang-Chi Technology is a global leader

Metamaterials refer to a type of composite materials that have artificially designed structures and exhibit extraordinary physical properties that natural materials do not have. Typical metamaterials that have come out so far mainly include left-handed materials, photonic crystals, supermagnetic materials, metallic water, etc. Metamaterials are a type of material that integrates semiconductor science, optoelectronics, classical optics, materials science and other disciplines as well as electronic engineering, nanotechnology, microwave, condensed matter physics and other technologies. It is widely used in national defense, aerospace, military communications, etc. High-precision fields have broad application prospects.

Stealth metamaterials refer to metamaterials used in the field of stealth. Current stealth technology can be divided into optical stealth, acoustic stealth, radar stealth, infrared stealth, laser stealth, etc. based on different detection methods. Among them, radar stealth is one of the important directions for the development of stealth technology. According to different stealth principles, it can be divided into two categories: shape stealth and material stealth. At present, radar stealth materials include radar absorbing materials, radar transmitting materials, electromagnetic metamaterials, etc.

According to the “2023-2028 Stealth Metamaterials Industry Market In-depth Research and Investment Prospects Forecast Analysis Report” released by the Industrial Research Center, Electromagnetic metamaterials are the latest development direction of the radar stealth materials industry and are one of the stealth metamaterials. Compared with other radar stealth materials, electromagnetic metamaterials have unique electromagnetic properties, micro-nano structures, sizes, arrangement and combination methods, and smaller resonant unit sizes. They are a stronger stealth material and will have great potential in the field of stealth in the future. Accelerated application will achieve true radar stealth.

At present, stealth capability has become one of the important indicators to measure the performance of modern weapons and equipment, and is a key point in the competition of weapons and equipment among various countries. As a key measure to effectively improve the stealth, combat performance and electronic warfare capabilities of missiles, ships, aircraft, armed helicopters and other weapons and equipment, the application of stealth materials has attracted increasing attention in the market. Among them, stealth metamaterials, as a new direction for the development of stealth materials, have become a key area of ​​research in various countries.

Stealth metamaterials belong to an industry with high barriers to technology, raw materials, and military product qualifications. It is still in the early stages of development and has a small number of companies. Only a few companies such as Kuang-Chi Technology and Shaanxi Huaqin are present in the domestic market. Among them, Guangchi Technology is a leading company in the stealth metamaterial industry in my country and even the world, and its stealth metamaterial products have been successfully used on the J-20 aircraft. At present, my country’s research and production technology related to stealth metamaterials has reached the international leading level, and the industry development trend is good.

At the same time, in recent years, with the importance of metamaterials increasingly highlighted, my country has established support for a number of metamaterial research projects, including the 863 Program, the 973 Program, the National Natural Science Foundation, and major new materials projects. Industry analysts said that in the future, the country will continue to pay more attention to stealth materials, metamaterials, and stealth metamaterials. Under the background of improvement, the research process related to stealth metamaterials in my country is expected to be further accelerated, and the industry development potential is huge.
