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.
