Emi Shielding Through Conductive Plastics

Abstract

Electromagnetic interference (EMI) received increasing amounts of press in the past few months, and will continue to do so in the future. Regulatory agencies in the United States have begun to come down hard on manufacturers of home computers and video games which link to television sets. These units, like the early CB radios, are adding additional electronic noise to the environmerit and interfering with sensitive electronics. Other forms of EMI are generated from natural sources, such as precipitation static, lightning storms, and solar flares. These natural sources, coupled with the largest source of EMI, legally operating transmitters which happen to operate in the range in which unintended receivers are susceptible, combine to form the “polution problem of the 80s”.
