Hi All,
    Adrian talked about basic topics for discussion. Here are a few
ideas.

1. TEM and TM modes in transmission lines or for EMC. What are the
assumptions that drive one or the other?

2. Differential signalling - broadside coupling or edge coupling,
differential mode ground and common mode ground, EMC implications for
different types of coupling.

3. Methods for describing more accurately the behavior of transmission
lines and return paths under changing frequency conditions.
Incorporation of dielectric losses in the simulation and/or
calculations. Incorporation of the harmonics of the digital signal with
corresponding changes in impedance to better emulate dispersion of the
digital signal that gives rise to jitter/skew.

These are just a few of the more esoteric concepts that I would like to
see discussed.

Thanks
Jim Freeman
