TCS EMI shielding gasket used on shielding room
Electromagnetic interference (EMI) shielding is put in place to attenuate (reduce the intensity of) RFI / EMI. Generally, a full enclosure around a component is formed using this shielding material, attenuating EM waves both leaving and entering.
In this way the shield protects the component in question from outside interference and significantly reduces any EM leakage. There are two ranges of electromagnetic shielding: Magnetic shielding and radio frequency shielding. By far the least common is of the two is Magnetic Shielding, used to protect against strong magnetic forces at low frequencies (anything below 100KHz). By utilising material with high magnetic permeability (such as Mu-metal or iron/steel), magnetic shielding attracts and then redirects magnetic fields away from whatever is being shielded. Strong magnetic forces are typically prevalent in areas with strong electric current, such as power plants or transformer rooms. These magnetic forces can be damaging to the health of a human. High frequencies (anything above 100KHz) require “Radio Frequency” shielding. Radio Frequency shielding utilises materials with high conductivity with very little magnetic permeability (such as copper mesh) to apply the Faraday effect to EM waves. All instances of EMI RFI listed in the earlier section are in the radio frequency range.
