Southern Finance All-Media Reporter Ou Xue Zhuhai Report
November 8-13, the 14th China International Aerospace Expo (hereinafter referred to as " China Air Show ") was held at the Zhuhai International Air Show Center.
At this China Air Show, many major powers were unveiled. Among them, in the field of cutting-edge equipment, the metamaterial technology used behind it once again attracted social attention.
What is metamaterial? Compared with the composition of traditional materials, the composition of metamaterials is no different. However, in terms of function, by manually changing or redesigning the microstructure of natural materials, metamaterials can have super-normal physical functions that natural materials do not have in acoustics, electrical, magnetics, , and optical. Therefore, metamaterials are also commonly understood as artificial materials with special properties. Thanks to the singular performance of metamaterials, its application scenarios are very wide. The related technologies derived from this have also penetrated into all walks of life, especially in many fields such as wireless communication , radar stealth, vibration reduction and noise reduction, thermal energy conversion, high-precision imaging, and high-sensitivity sensing.
In China, the productization path of metamaterial experimental results has accelerated, and some metamaterial concept stocks have also been born, such as LightQi Technology, Diweixun, Pengxin Resources , Days and Defense , Jinyun Laser , etc.
At this China Air Show, metamaterials ushered in new progress again. As the only company in China to industrialize metamaterials technology, Guangqi Technology has released the fourth generation of metamaterials.
At the China Air Show, Liu Ruopeng, chairman of Guangqi Technology, told the reporter of Southern Finance and Economics, "The fourth generation of metamaterial technology is a new generation of metamaterial technology that can realize the engineering application of three-dimensional metamaterials. Compared with the previous generation of metamaterial technology, it has achieved major technological breakthroughs from two-dimensional to three-dimensional three-dimensional design and upgraded and improved metamaterial manufacturing process."

realizes a technological breakthrough from two-dimensional to three-dimensional three-dimensional design
The concept of metamaterials has attracted global attention. In 2001, Professor David Smith of the University of California, San Diego achieved negative refraction with metamaterials and subsequently published in the journal " Science ", promoting the establishment of the metamaterial discipline.
looks around the world, especially in the military field. The technological progress of metamaterials will promote the birth of a new generation of cutting-edge equipment, and all countries attach great importance to the research of metamaterials.
According to public information, the US Department of Defense has specially launched a research project on metamaterials, and Intel , AMD and IBM have also established a joint fund to fund this research. At the same time, in China, the development model in the field of metamaterials is more focused, and metamaterial research is supported in some major new materials projects and other projects.
metamaterials have a wide range of applications and have important military and civilian value. At present, in the military field, metamaterial technology helps to achieve efficient electromagnetic wave absorption, thereby realizing aircraft stealth. In the civil field, a scientific research team in my country has used 3D printing to manufacture metamaterials, effectively solving the realization of metamaterial microstructures.
For light-acting technology, its metamaterials have been used in multiple cutting-edge equipment fields such as advanced aircraft, large drone , marine aviation equipment, electronic communication systems, individual AI equipment, etc., achieving full coverage of "flying in the sky, running on the ground, swimming in the water, and underwater". Especially in the field of aviation and marine equipment, the electromagnetic functional structural parts of optical technology have advantages in electromagnetic modulation, integrated radio frequency sensing, and integrated functional structures.
Regarding the newly released fourth-generation metamaterial, Liu Ruopeng said that the fourth-generation metamaterial has a wider range of applications, not only on key parts of the fuselage, but also on the entire body of the equipment. He further stated that the development of the fourth generation of metamaterials is closely related to the development of Chinese equipment. The relationship between metamaterials and equipment is essentially the pull of equipment on materials and the support of materials on equipment.
reporter learned that in terms of technology, the fourth generation of metamaterial technology allows metamaterial microstructure to achieve omnidirectional high-performance wave absorption through three-dimensional honeycomb design; in terms of technology, new process molding technology is adopted to achieve perfect matching of two-dimensional impedance , and break through the limitations of traditional processes in size, from finite size to approximately infinite size.
At the same time, Liu Ruopeng said that the fourth generation of metamaterial technology has three major characteristics. First, it has an order of magnitude improvement in many key indicators, second, it has a larger ultra-large bandwidth characteristic, and third, it is the process manufacturing structure, which can make the weight lighter.
Acceleration of Metamaterial Industrialization
In recent years, my country has attached great importance to metamaterial research. With the support of the country and the efforts of scientific researchers, China's metamaterial technology has developed rapidly. At present, my country has achieved original results in some research content, including basic research such as electromagnetic black holes, metamaterial stealth technology dielectric metamaterials, and negative refraction of sound waves.
At the same time, many universities have highlighted the research results. Zhejiang University has developed perfect wave absorbing materials based on slow wave design based on slow waves; Southeast University has developed radar hallucination devices, far-field super-resolution imaging lenses, new radomes, polarization converters and other new metamaterial devices; Tsinghua University has developed super-magnetic dielectric metamaterials based on ferromagnetic resonance, polarity lattice resonance, rare earth ion electromagnetic dipole transition, and Mie resonance .
According to Stratistics MRC forecast, by 2022, the global metamaterial market size will reach US$2.63 billion, with a compound growth rate of 23.2% from 2016 to 2022, and the metamaterial market has broad prospects. Although
has made some breakthroughs in technology, overall, my country is still a certain distance from the large-scale industrialization of metamaterials. Like other metamaterial companies, Light Technology also faces the problem of industrialization. From the laboratory to the product, solving the problem of large-scale manufacturing of large-volume metamaterials is the key.
Guangqi Technology is an early enterprise in China that began the industrialization of metamaterials. It has started the construction of related production bases since 2017. By the end of the first phase of Shenzhen Guangqi Technology 709 Base project in 2020, marking that metamaterials have entered the stage of large-scale production.
The acceleration of the industrialization process has driven the acceleration of the revenue growth of LightQuan Technology. According to the company's financial reports in recent years, Guangqi Technology's operating income from 2018 to the first three quarters of 2022 was RMB 464 million, RMB 481 million, RMB 637 million, RMB 859 million and RMB 835 million, respectively, with growth rates of 22.14%, 3.78%, 32.25%, 35.01%, and 117%, respectively.
At the China Air Show, Liu Ruopeng revealed that Guangqi launched the second phase of the 709 base in the second half of this year, and construction is expected to start at the end of the year. At present, Guangqi Technology has sufficient orders in hand. Starting from the end of this year, a large number of new orders have been transferred to small batch production. After the second phase is completed, all developed products involved will enter large-scale batch production. "When the second phase is completed and put into production, we will truly enter a comprehensive and large-scale production." Liu Ruopeng said.
At the same time, Liu Ruopeng added that after the Spring Festival next year, the production lines of the fourth generation of metamaterials will be completed.
