Recently, Chu Junhao, an academician of the CAS Member, showed a video of using special materials to achieve "invisibility". "In the future, with the gradual maturity of 'stealth' technology and metamaterials, the invisibility imagination in science fiction works will gradually move towards reality." In the video, Chu Junhao said, "I believe there will be more 'stealth' equipment that will change our lives in the future." The metamaterials mentioned by Chu Junhao have been applied in fields such as electromagnetism, acoustics, mechanics, thermodynamics, and quantum. The concept of metamaterials originated in the 1960s, but it was not until the early 21st century that people truly paid attention to it. The so-called metamaterial refers to a composite material that precisely regulates the physical field at the sub wavelength scale through artificial microstructures. By precisely designing and controlling the microstructure, researchers can enable metamaterials to form new functional structures. With the rapid development of metamaterial technology, researchers have applied it to various advanced equipment, and the related technologies derived from it have also produced disruptive effects in multiple fields. "In the past 20 years, the first stage was focused on basic research, and the second stage was focused on the entire industry 'concentrating efforts' to promote metamaterials from the laboratory to the engineering stage." Liu Ruopeng, Chairman of Guangqi Technology Co., Ltd. (hereinafter referred to as Guangqi Technology), believes that after nearly 10 years of development, metamaterial technology has become an indispensable mainstream technology in the field of new equipment research and manufacturing. In the field of aerospace equipment, metamaterials can be used to manufacture lightweight and high-strength spacecraft materials, improving the performance of space probes and satellites. In the medical field, the acoustic properties of metamaterials can be utilized to achieve higher resolution medical images. "Nowadays, there are three new changes in metamaterials. Firstly, the application and functionality of metamaterials are constantly increasing, from the initial edge technology or emerging technology to the current mainstream technology. Secondly, metamaterial technology has achieved updates and iterations from the third generation to the fourth generation, and has begun to enter large-scale applications. Thirdly, the application of metamaterials is showing an order of magnitude change." Liu Ruopeng said. Recently, the Ministry of Industry and Information Technology and the State owned Assets Supervision and Administration Commission of the State Council jointly released the first batch of key development guidance catalogs for the industrialization of cutting-edge materials, and metamaterials were included in this catalog. "In recent years, our main work has been to strive for the large-scale production of fourth generation metamaterial technology products." Liu Ruopeng introduced that the fourth generation metamaterial technology has overturned previous technological cognition. At present, the fourth generation metamaterial technology has made significant breakthroughs and entered the application stage. Some products expected to be delivered by the end of this year or early next year will be applied to fourth generation metamaterial technology. In recent years, China's new materials industry has developed rapidly and its scale has continued to grow. However, due to the high technological threshold and long research and development cycle of cutting-edge material production, its application still needs further exploration. "Objectively speaking, the development space of the metamaterial industry is very large, and its development will affect more industries. However, if we want to continue in-depth research on metamaterials, we still need to have a relatively clear definition and definition. In a period when the development of a discipline is becoming more prosperous, it is more necessary to be calm and cautious." Liu Ruopeng emphasized that any new technology from the laboratory to industrialization has a common law, and we should respect its common characteristics
