ABSTRACT
Electromagnetic compatibility (EMC) is a field of science and engineering concerned with the design and operation of electrical and electronic systems/devices in a manner that makes them immune to certain amounts of electromagnetic interference (EMI), while at the same time keeping their EMI emissions within specific limits. With the rapid increase in the use of telecommunications, digital systems, fast processors, and the introduction of new design practices, EMC has been brought to the forefront of advanced design. This includes minimizing EMI generation at its source, reducing or eliminating coupling paths by proper layout; shielding, filtering, and grounding practices; designing hardware with an inherent immunity to EMI; and adopting defensive programming practices to develop software that has a high level of immunity to EMI (Christopoulos, 1995). In these approaches, EMI shielding is an important and effective method in EMC design. Certainly, advanced materials and process technology is the key to achieving successful EMI shielding.
