Summary
This three-day course is designed for technicians,
operators and engineers who need an understanding
of Electromagnetic Interference (EMI)/Electromagnetic
Compatibility (EMC) methodology and concepts. The
course provides a basic working knowledge of the
principles of EMC.
The course will provide real world examples and
case histories. Computer software will be used to
simulate and demonstrate various concepts and help
to bridge the gap between theory and the real world.
The computer software will be made available to the
attendees. One of the computer programs is used to
design interconnecting equipments. This program
demonstrates the impact of various EMI “EMI
mitigation techniques" that are applied. Another
computer program is used to design a shielded
enclosure. The program considers the box material;
seams and gaskets; cooling and viewing apertures;
and various "EMI mitigation techniques" that may be
used for aperture protection.
There are also hardware demonstrations of the effect
of various compromises on the shielding effectiveness
of an enclosure. The compromises that are
demonstrated are seam leakage, and a conductor
penetrating the enclosure. The hardware
demonstrations also include incorporating various "EMI
mitigation techniques" and illustrating their impact.
Instructor
Dr. William G. Duff (Bill) is an independent
consultant. Previously, he was the Chief
Technology Officer of the Advanced
Technology Group of SENTEL. Prior to
working for SENTEL, he worked for
Atlantic Research and taught courses on
electromagnetic interference (EMI) and
electromagnetic compatibility (EMC). He
is internationally recognized as a leader
in the development of engineering technology for
achieving EMC in communication and electronic
systems. He has 42 years of experience in EMI/EMC
analysis, design, test and problem solving for a wide
variety of communication and electronic systems. He
has extensive experience in assessing EMI at the
equipment and/or the system level and applying EMI
suppression and control techniques to "fix" problems.
Bill has written more than 40 technical papers and
four books on EMC. He also regularly teaches seminar
courses on EMC. He is a past president of the IEEE
EMC Society. He served a number of terms as a
member of the EMC Society Board of Directors and is
currently Chairman of the EMC Society Fellow
Evaluation Committee and an Associate Editor for the
EMC Society Newsletter. He is a NARTE Certified EMC
Engineer.
