Popular niche technology: 8-12 GHz magnetic absorbing materials ignite innovation trend!

In recent years, with the continuous advancement of technology, magnetic absorbing materials have attracted great attention in niche technological fields. The emergence of this material has significantly improved the measurement of characteristic impedance coupling in electronic devices, radar or communication equipment such as antennas, missiles, aircraft and satellites, the measurement of astronaut's shoulder antenna pattern, and the installation, testing and adjustment of spacecraft. Meanwhile, magnetic absorbing materials can also improve the compatibility of airborne and shipborne radar equipment and enhance overall performance. This article will delve into the absorption effect of 8-12 GHz magnetic absorbing materials and their applications in various fields.

The absorption effect of magnetic absorbing materials:
The absorption effect of such magnetic absorbing materials is closely related to the incident wave frequency and coating thickness. As an example of products currently available both domestically and internationally, coatings with a thickness of 1.5-2mm can achieve peak absorption rates of 98% -99% at selected frequencies between 8-12 GHz. Beyond the two peaks, the coating can still absorb 90% -97%. In addition, there is a thin film with a thickness of 0.5-1.5mm that can achieve 97% absorption at 10-12GHz. However, when it drops to 6GHz or rises to 16GHz, the absorption rate will decrease to 75%. Therefore, the advantage of coated absorbing materials is that they can achieve a reduction in radar cross section without changing the shape of the aircraft.

Application areas of magnetic absorbing materials:
1. Interference from electronic devices: Magnetic absorbing materials can effectively absorb electromagnetic waves, reduce interference between electronic devices, and improve device performance and stability. Their applications in mobile phones, computers, and other electronic devices have been widely adopted.

2. Radar and communication equipment: In radar or communication equipment such as antennas, missiles, aircraft, and satellites, the application of magnetic absorbing materials can significantly reduce the coupling of characteristic impedance, improve the transmission efficiency and reception sensitivity of the equipment. This is of great significance for the development of national defense security and communication fields.

3. Measurement of astronaut's back shoulder antenna pattern: The characteristics of magnetic absorbing materials enable precise measurement of astronaut's back shoulder antenna pattern, thereby improving the navigation accuracy and communication effectiveness of spacecraft.

4. Spaceship testing and adjustment: Magnetic absorbing materials can be used in the installation, testing, and adjustment process of spacecraft to reduce electromagnetic interference between internal and external devices, ensuring the normal operation of the spacecraft.

5. Improving the compatibility of radar equipment: The application of magnetic absorbing materials in airborne and shipborne radar equipment improves the compatibility of the entire machine, thereby enhancing the efficiency and stability of radar equipment and further promoting the development of radar technology.
6. Improving the performance of airborne radar equipment: Due to the characteristics of magnetic absorbing materials, the overall performance of airborne radar equipment has been improved, making the aircraft more stealthy in electromagnetic environments and greatly reducing the possibility of being detected by the enemy.

Conclusion:
In summary, the emergence of 8-12 GHz magnetic absorbing materials has attracted widespread attention in the field of technology. Their applications in various fields have brought tremendous improvements and innovations in interference of electronic devices, measurement of characteristic impedance coupling of antennas, missiles, aircraft, and satellites in radar or communication equipment, measurement of directional patterns of back shoulder antennas for astronauts, installation testing and adjustment of spacecraft, and improvement of compatibility of onboard and shipborne radar equipment. With the continuous advancement of technology, it is believed that magnetic absorbing materials will have a wider range of applications in the future and bring more innovation and breakthroughs to the development of various industries.
