Why Electromagnetic Interference (EMI) Sheilding?
EMI shielding is a critical aspect of the defense industry, as it helps to protect sensitive electronic equipment from electromagnetic interference (EMI). This interference can come from a variety of sources, such as radio frequency transmissions, power lines, and even the sun. Without proper EMI shielding, electronic equipment can malfunction or even fail completely, putting lives and missions at risk.
The importance of EMI shielding in the defense industry cannot be overstated. In battlefield situations, for example, electronic equipment is subjected to a wide range of environmental conditions, including extreme temperatures, humidity, and dust (see MIL-STD-810). EMI shielded systems are often rugged in nature and are built to protect this equipment from these harsh conditions, ensuring that it continues to function properly and perform its intended mission.
Another important aspect of EMI shielding in the defense industry is its ability to protect against electronic warfare (EW) threats. These threats include jamming and spoofing, which can be used to disrupt or degrade the performance of electronic equipment. EMI shielding helps to protect against these threats by providing a barrier between the equipment and the source of the interference. ProCustom Group has specifically developed various solution to protect against these events (e.g. HEMP Hardening). While MIL-STD-461 covers a lot of the emissions/susceptibility risks – there are often more extreme scenerios that must be accounted for when designing an EMI shielded system.
There are many different types of EMI shielding materials and techniques that are used in the defense industry, including conductive coatings, metal enclosures, and electromagnetic wave absorbers. Each of these has its own unique set of properties and benefits, and the choice of which to use will depend on the specific application and the level of protection required.
