Absorbing material generally refers to a type of material that can absorb the electromagnetic wave energy projected on its surface. In engineering applications, in addition to requiring high absorption of electromagnetic waves in a wide frequency band, the absorbing material is also required to have light weight, temperature resistance, humidity resistance, and corrosion resistance. With the development of modern science and technology, electromagnetic waves The impact of radiation on the environment is increasing. At the airport, the flight is delayed due to electromagnetic interference. Mobile phones often interfere with the normal operation of various electronic medical equipment.
For radar electronic reconnaissance and counter reconnaissance, a lot of exploratory work has been carried out on electromagnetic wave absorbing materials. With the rapid development of telecommunications services, absorbing materials have also been applied to many fields such as communications, environmental protection, and human protection. Capital to increase research on absorbing materials.
The surface of various radar targets is coated with absorbing materials to reduce the effective reflection cross-section of the weapon system, so that these weapons can easily break through the enemy's radar defense zone. This is a powerful means of anti-radar reconnaissance and also reduces weapon systems. A method of being attacked by infrared guided missiles and laser weapons. Absorbing materials can also be used for landing lights and other airport navigation equipment, ship masts, decks, submarine periscope brackets or air ducts, etc.
Absorbing materials are used in various electronic products, such as TVs, stereos, VCD players, computers, game consoles, microwave ovens, mobile phones, and can reduce electromagnetic wave leakage to the national health safety limit and ensure human health. Applying it to high-power radars, microwave medical devices, and microwave crushers can protect operators from electromagnetic radiation.
Method/Step
1 Microwave absorbing materials are used as auxiliary materials for microwave anechoic chambers, including flat type and support type, which are used for walking testers in microwave anechoic chambers.
2 Place it on the side wall of the microwave anechoic chamber to reduce the impact on the performance of the microwave anechoic chamber. The wear-resistant cloth is upward, and it is recommended that personnel wear soft-soled shoes when entering and leaving.
