| Following are two very different types of papers concerning a common
issue, grounding, and a third which presents a useful modeling tool for designers of
digital communications systems. Professor Takeo Yoshino of Fukui University of Technology
in Japan describes some unusual grounding problems encountered more than 40 years ago
during an Antarctic research expedition, and resulting lessons learned which apply even to
modern systems. Doug Smith, an independent consultant based in Los Gatos, CA, describes an
interesting current probe which can be used to locate noisy circuit board grounds.
Panagiotis Trakadas, currently working on his Ph.D. thesis at National Technical
University of Athens (Greece), and Christos Capsalis, a Professor at NTUA, present an FDTD
modeling approach that suggests the importance of considering non-uniformity of
transmission line configuration when assessing the coupling effects of external EM fields. EMCS
members are encouraged to submit original papers and articles based on their own practical
EMC experience for publication in this section of the Newsletter. Effective with the next
issue, submittals should be forwarded to Bob Olsen at Washington State University ( olsen@eecs.wsu.edu ), who will take on the job
of Associate Editor. I have been privileged to serve in this capacity for the past four
years and have enjoyed working with the many authors who responded to our calls for
papers. I have also greatly appreciated the strong support of Editor Janet O'Neil, who was
especially active in recruiting and encouraging authors, and the production expertise of
Robin Edwards and Andrea Watson, the IEEE Newsletter coordinators in Piscataway. |
