EMI Shielding RF Pure Copper Wool For Anechoic Chamber
The main purpose of effective EMC shielding is to prevent electromagnetic interference (EMI) or radio frequency interference (RFI) from impacting sensitive electronics. This is achieved by using a metallic screen to absorb the electromagnetic interference that is transmitted through the air. The shield effect is based on a principle used in a Faraday cage—the metallic screen completely surrounds either the sensitive electronics or the transmitting electronics. The screen absorbs the transmitted signals, and causes a current within the body of the screen. This current is absorbed by a ground connection, or a virtual ground plane.
By absorbing these transmitted signals before they reach the sensitive circuitry, the protected signal is kept clean of electromagnetic interference, maximizing shielding effectiveness. A good example is the smartphone. It is essential that EMC shielding protects the sensitive electronics in the device that make it process and display information from the phone’s transmitter.
