Do not read electromagnetic shielding knowledge
With the rapid development of electronic technology, people use more and more electronic products and equipment in production and life, and computers, radio and other transmitters will produce electromagnetic waves of different wavelengths and frequencies. At present, electromagnetic pollution has become a new source of pollution after air pollution, water pollution and noise pollution. Therefore, people pay more and more attention to electromagnetic shielding of related equipment.

Electromagnetic shielding, is the use of metal and other electromagnetic shielding materials made of shielding, the need to protect the area closed up, the electromagnetic pulse isolation in the shield, the need for ventilation and access to personnel and equipment of the aperture is protected by electromagnetic shielding doors or waveguide Windows. When the electromagnetic pulse comes, its electromagnetic energy is reflected, absorbed or blocked by the shield. Even if the electromagnetic pulse can penetrate the shield, the electromagnetic energy and electromagnetic field strength will decay to an acceptable degree.
Electromagnetic shielding is one of the important measures to avoid electromagnetic interference of electronic equipment and electronic system, which can effectively reduce the electromagnetic interference leaked by space propagation. It can not only reduce the electromagnetic interference from the electronic equipment, but also prevent the influence of external electromagnetic interference on the electronic equipment.
