EMC Experiments/Demonstrations

Elya Joffe:

Currents if not Obstructed will Always Flow in the Part of….

Abstract: Few principles in EMC are confusing as much as those of "Grounding" and "Shielding".
Indeed, misconceptions as to the mechanisms of those techniques have led to many wrong concepts and implementations, which today are extremely difficult to uproot: Is it better to use single point or multipoint grounding? In Which frequencies? Is it better to ground a shield at both ends or at one only? And how about the Signal circuits? How does return current flow on the PCB - does it follow the shortest path?
The key to the answer to all those questions lies within the domain of a concept called: "The Path of Least Inductance". That is the path that current will follow at high frequencies (what is "high" for this purpose?)
This lecture will discuss the very important concept of the "Path of Least Inductance", and the application of this principle for providing answers to the above questions and others.

Biography: Mr. Joffe is employed by K.T.M. Project Engineering, an engineering consulting company, in Israel since 1987. He currently holds a position of the V.P. of Engineering and works as a Senior EMC engineering Specialist and consultant.

Mr. Joffe served as a “Distinguished Lecturer” of the IEEE EMC Society, for the years 1999 through 2000.
Mr. Joffe received several awards from the IEEE and EMC Society for his activities. In particular, he is a recipient of the prestigious “Lawrence G. Cumming Award” (2002), the “Honorary Life Member Award” (2004), the IEEE EMC Society “Technical; Achievement Award” (2004), the IEEE EMC Society “Symposium Chair Award” (2004) and the IEEE “Third Millennium Medal” “…in recognition and appreciation of valued services and outstanding contributions”.

Antonio Šarolić:

Electromagnetic Field Measurement for Modulated RF Signals with Arbitrary Waveforms

Experiment demonstration: Since electric field probes are commonly calibrated with a single sine signal, they react differently to signals that are modulated with different modulations. This can lead to significant error when measuring such signals. This error is unknown if the incident signal waveform is unknown (common case) and if the probe response to modulated signals is unknown (even more common case). An experiment will be performed to demonstrate such an error. The setup consists of an arbitrarily modulated signal generator, average power meter, controlled EM environment (rectangular waveguide) and two different electric field probes. The average signal power is controlled and kept constant, while the probes measure the RMS field inside the waveguide. The measurement results will demonstrate discrepancy and measurement errors when measuring the same average signal power but with different probes and different modulations of incident signal.

Biography: Dr. Šarolić is Assistant Professor in Electrical Engineering at University of Split, FESB, Department of Electronics. He was previously employed by University of Zagreb, FER, Dept. of radiocommunications. His areas of interest are electromagnetic measurements, bioeffects of EM fields, electromagnetic compatibility (EMC) and radiocommunications. He has been working on several research projects and has authored over 40 papers in previously named topics. Dr. Šarolić has also worked on numerous technical expertises for EE companies. He is involved in standardization process through various committees and working groups.
