Applying Practical EMI Design and Troubleshooting Techniques
This two-day course on 19 and 20 June gives engineering professionals the ability to successfully recognize, solve and avoid challenging EMI problems.
Demonstrations using working hardware illustrate concepts such as radiated emissions, high frequency antennas, radiated and conducted immunity and crosstalk in connectors, cables and IC packages.
Integrating over 30 years of hands-on troubleshooting experience and the latest EMC research, this course is appropriate for experienced circuit and system design engineers, EMC engineers, as well as those who are new to EMI problem solving.

Lee Hill is Founding Partner of SILENT Solutions LLC, an electromagnetic compatibility (EMC) consulting firm he started in Silicon Valley in 1992. He is also Managing Director of Silent Solutions GmbH (Munich).
He received his MSEE with highest honors from the Missouri University of Science & Technology EMC Laboratory emclab.mst.edu, where he studied under Dr.’s Thomas Van Doren, Todd Hubing, and James Drewniak.
Lee teaches a graduate course in EMC as a member of adjunct faculty at Worcester Polytechnic Institute (WPI), and is also an EMC course instructor for University of Oxford (England), and for the IEEE EMC Society's annual Global University and Fundamentals Program. Lee is the named inventor of three US patents for EMI control in electronic systems, and provides expert witness services for patent litigation. While teaching is one of Lee’s favorite jobs at SILENT, the majority of his time is spent providing hands-on hardware troubleshooting of / and design reviews to prevent elusive regulatory and functional electrical noise problems.
Lee is a past EMC course instructor for the University of California Berkeley Extension, Hewlett-Packard, Agilent, Freescale Semiconductor, and General Motors University. Previously Lee was Principal EMC and Systems Engineer at Digital Equipment Corporation’s Workstation Systems Engineering Group in Palo Alto, California. With over 25 years of EMC design and troubleshooting experience, Lee consults and teaches worldwide, and has been teaching short courses on EMC design and troubleshooting for twenty years, He has presented EMC courses in Taiwan, Singapore, Mexico, Norway, Canada, South Korea, Germany, France, and United Kingdom.
Lee frequently volunteers for the IEEE EMC Society and currently chairs the annual IEEE EMC Symposium’s Fundamentals program & is an instructor for the Symposium’s Global University Program. He is also a past member of the IEEE EMC Society's Board of Directors (2004-2007), and has also served as a member of the Society’s Awards Committee. In 1994, Lee was appointed to serve a two year term as an IEEE EMC Society Distinguished Lecturer (DL), and from 1999-2006 he served as chair of the DL program. Over the past twenty years Lee has been a frequent featured speaker at IEEE EMC Society fundraising events in cities throughout the US including Santa Clara, Seattle, Portland, Chicago, Milwaukee, Dallas/Fort Worth and Detroit. He has also provided technical presentations to Society chapters in Los Angeles, San Diego, Boston, Austin, Atlanta, Colorado Springs, Pittsburgh, and Orange County, CA.
