What Is Electromagnetic Shielding (EM Shielding)?

You've probably never heard of Electromagnetic Shielding (EM Shielding), but it's a significant player in your life. Electromagnetic waves are everywhere. They're in your cell phone and computer, they play a role in radio transmissions, and they're the reason you can use your remote control to change channels on your TV—and why you can get reception inside your house. Sometimes, we don't want certain electromagnetic waves around us. For example, suppose you use an electric blanket or a microwave oven. In that case, you'll want to be sure that those devices don't leak outside their intended area with electromagnetic waves, or maybe you want to ensure that no one else can listen in on your conversations by listening to electromagnetic waves emitted from your phone or laptop (spoiler alert: they can). If you're looking for a way to protect your space from radio frequency identification (RFID) signals, look no further than our RFID shielding systems. These systems are designed to seal out radio waves to protect an internal area from wireless signals or requests for information conducted over radio frequency waves. They're not just good for protecting sensitive information; they also help keep the integrity of your product intact. That's because many products use wireless chips to communicate with one another, so if other waves or signals disrupt those chips, it could make them less effective. If you've ever wondered why your microwave has a metal lining, this is why. The metal lining in microwaves shields you from the electromagnetic radiation from the device. It's not just the microwave—shielding can be found in all electrical appliances. One example of electromagnetic shielding is shielded cabling, which keeps electromagnetic fields contained within its walls and out of the air around it. This shielding is often used in hospitals and other medical facilities, where electromagnetic interference can cause severe problems with sensitive equipment. Another type of electromagnetic shielding is called a Faraday cage, which blocks out all incoming electromagnetic fields (including radio signals) from an interior space. You may have heard stories about people who could make their Faraday cages by covering themselves with aluminum foil—precisely what they were doing!
