Disclaimer! Clever Application of Ferrite Absorbing Materials in Radar Technology

Radar is no longer being monitored by enemies! Ferrite absorbing materials lead the invisible technology revolution

With the continuous development of technology, the demand for stealth technology in the military field is becoming increasingly urgent. In terms of achieving radar stealth effect, ferrite absorbing materials are considered a very effective solution. Advanced Institute Technology's ferrite absorbing materials have excellent absorbing properties, which can effectively absorb and dissipate radar waves to prevent enemy surveillance.

The research history of ferrite absorbing materials is relatively long, dating back to earlier times. According to their different structures, ferrite absorbing materials can be divided into two types: spinel type and hexagonal ferrite. Spinel ferrite absorbing materials have the advantages of simple preparation process and long application history. However, due to their low magnetic permeability, it is difficult to match with the relative dielectric constant and relative magnetic permeability, making it challenging to achieve good absorbing performance.

Lockheed Martin used a large amount of ferrite absorbing materials as absorbing coatings in the development of the F-117A fighter jet to achieve excellent radar stealth performance. This enables the F-117A fighter jet to reduce reflections within the radar monitoring range, effectively protecting the aircraft.

Japan Electric Corporation has made significant progress in improving ferrite absorbing materials. The ferrite absorbing material they developed has an absorption effect of -10dB in the range of 6-13GHz, and the absorption effect can even reach -20dB in the range of 8.5-12.2GHz. Its total thickness is about 4.7mm, and the mass per unit area is only 8kg/m ². This technological breakthrough not only expands the application range of ferrite absorbing materials, but also further enhances the development of stealth technology.

However, although research on ferrite absorbing materials is relatively mature abroad, the level of research and application in China is relatively low. In the frequency range of 8-18GHz (X, Ku band), the electromagnetic wave reflectivity in China can only reach a level of -10dB. Compared with foreign countries, we still face technological bottlenecks and insufficient development.

Therefore, strengthening the research and application of ferrite absorbing materials has become an urgent task at present. Although attempting to apply ferrite absorbing materials to military equipment and aircraft is a complex and time-consuming process, it will undoubtedly greatly enhance our military's stealth capabilities and improve our combat advantages in strategic environments.

In summary, with the continuous improvement and application of ferrite absorbing materials, radar stealth technology has achieved significant breakthroughs. Although the research level in China is relatively lagging behind, as long as we increase investment, strengthen cooperation with foreign countries, and learn from successful cases such as Japan Electric Company, we believe we can catch up and lead the wave of invisible technology revolution, achieving the goal of radar no longer being spied on by enemies!
