Instructor
Dr. William G. Duff (Bill) received a BEE degree
from George Washington University
in 1959, a MSEE degree from
Syracuse University in 1969, and a
DScEE degree from Clayton
University in 1977.
Bill is an independent consultant
specializing in EMI/EMC. He worked
for SENTEL and 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 more than 40 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 circuit, equipment and/or the
system level and applying EMI mitigation
techniques to "fix" problems. Bill has written more
than 40 technical papers and four books on EMC.
He is a NARTE Certified EMC Engineer.
Bill has been very active in the IEEE EMC
Society. He served on the Board of Directors, is
currently Chairman of the Fellow Evaluation
Committee and is an Associate Editor for the
Newsletter. He is a past president of the IEEE EMC
Society and a past Director of the Electromagnetics
and Radiation Division of IEEE.
What You Will Learn

• Victim Sensitivities.
• Common Ground Impedance Coupling.
• Ground Loop Coupling.
• Shielding Theory.
Summary
This three-day course is designed for
technicians, operators, and engineers who need
an understanding of all facets of grounding and
shielding at the circuit, PCB, box or equipment
level, cable-interconnected boxes (subsystem),
system and building, facilities or vehicle levels.
The course offers a discussion of the qualitative
techniques for EMI control through grounding and
shielding at all levels. It provides for selection of
EMI suppression methods via math modeling and
graphics of grounding and shielding parameters.
Our instructor will use computer software to
provide real world examples and case histories.
The computer software simulates and
demonstrates various concepts and helps 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
grounding schemes and different "fixes" 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
"fixes" that may be used for aperture protection.
There are also hardware demonstrations of the
effect of various compromises and resulting
"fixes" 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 "fixes" and illustrating their
impact.
