Testing EMI gaskets with Transfer Impedance and Shielding Effectiveness methods

摘要

Today's electronic equipment must be designed to, first, operate in the electromagnetic (EM) environment it is to be employed in, and second, ensure that the EM fields generated by the system do not add significantly to the EM environment. These steps are accomplished by having the equipment housing simulate a "Faraday Cage" (that is, the electronic system functions properly without adding to the EM environment). The proper selection and use of an EMI gasket to seal the seams of an enclosure is the secret to obtaining a simulated Faraday Cage.
