Electromagnetic interference (EMI) generated by electromagnetic wave radiation not only affects the normal operation of various electronic devices, but also harms health. As plastic products are gradually replacing traditional materials, electromagnetic shielding technology is becoming more and more important. Today, I will take you to understand the application of low-wave absorbing materials.
There are many tall buildings in the city, and the reflection of electromagnetic waves by tall buildings can cause ghosting. Applying absorbing materials to building materials can solve this problem. The microwave anechoic chamber made of absorbing materials can be widely used in the fields of radar, communication and aerospace. In addition, absorbing materials also have broad application space in improving the compatibility of airborne and airborne radar equipment and improving the performance of the whole machine. .
On the surface of various radar targets, coating 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 the weapon system. 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. Applying absorbing materials to various electronic products, such as TVs, LED displays, stereos, VCD players, computers, digital cameras, game consoles, microwave ovens, and mobile phones, can reduce electromagnetic wave leakage to the national health safety limit (10 Microwatts per square centimeter) to ensure human health. Applying it to high-power radar, microwave anechoic chamber, microwave medical device, microwave crusher, electronic compatible absorption shield, can protect the operator from electromagnetic radiation.
Today, Japan and some developed countries have applied microwave absorbing materials to a large range. Up to now, our Chinese market has gradually introduced absorbing materials into practical products. It is predicted that the scale of Chinese market demand will be the same as Japan, and may even surpass Japan next year. In daily life, such as smart payment mobile phones, POS machines, various smart cards, RFID radio frequency cards, RFID readers, card readers, various smart access control, WIF, antennas, etc., almost everyone in the streets and alleys. In the future, people's demand for these will be greater and they will be used more and more frequently. In addition, the demand for anechoic chambers in China is increasing, and the prospects for composite absorbing materials are promising.
