An EMC/RF anechoic chamber is a room designed to completely absorb reflections of electromagnetic waves. They are also often isolated from microwaves entering from their surroundings. This combination means that a device exclusively receives direct waves (no reverberation waves), in effect simulating being inside an infinitely large room.
RF Shielded rooms provide the necessary RF quiet environment in which to conduct many different application tests such as EMC, wireless technology on automotive or military vehicles, MRI scans, etc. These rooms are built with Smart shield TM modular RF shielding, electromagnetic pulse protection EMPP shielding TEMPEST (secure communications) shielding and architectural shielding full systems.
RF Shielded racks/boxes are RF shielded enclosures for information security/interference or small devices testing inside. Usually they require lower attenuation than shielded rooms and anechoic chambers.WEMC filters for Shielded Rack/Box are designed specifically for compact applications, usually less weight and low leakage.
Electromagnetic pulse (EMP), also sometimes called a transient electromagnetic disturbance, is a short burst of electromagnetic energy. Such a pulse's origin may be a natural occurrence or man-made and can occur as a radiated, electric, or magnetic field or a conducted electric current, depending on the source.
With EV/PHEV are getting more and more popular, related standards have been set increasingly, EMI has become a non-negligible issue with the driving system. WEMC offers filters for electric driving system, including Wuling, Hezhong, Tianji…etc., many famous car brands in China are equipped by WEMC filters.
