Shielding of Electromagnetic Waves

This book provides a new, more accurate and efficient way for design engineers to understand electromagnetic theory and practice as it relates to the shielding of electrical and electronic equipment.  The author starts by defining an electromagnetic wave, and goes on to explain the shielding of electromagnetic waves using the basic laws of physics. This is a new approach for the understanding of EMI shielding of barriers, apertures and seams. It provides a reliable, systematic approach that is easily understood by design engineers for the purpose of packaging the electrical and electronic systems of the future.  This book covers both theory and practical application, emphasizing the use of transfer impedance to explain fully the penetration of an electromagnetic wave through an EMI gasketed seam. Accurate methods of testing shielding components such as EMI gaskets, shielded cables and connectors, shielded air vent materials, conductive glass and conductive paint are also covered.

  George M. Kunkel

George M. Kunkel, has been an EMC design engineer for over 50 years of his life. He earned both his B.S. and M.S. degrees in engineering at UCLA. The first 30 years of his career was spent accepting full responsibility for the EMC design and test of systems. His professional responsibilities include being Chairman of the Technical Committee on Interference control for an 18 year period (1969 to 1987) and Chairman of a Shielding Theory and Practice working group over a period of six years (2002 through 2008) of the EMC Society of the IEEE. Mr. Kunkel has written and presented over 100 technical articles at various IEEE sponsored International Symposia and edited professional publications. He also taught courses on EMC System Design at UCLA extension.
