Hi,

You may want to do a little research from the website

     www.emclab.umr.edu

University of Missouri-Rolla is heavily involved in
EM numerical modeling techniques.

Hello all,

I am looking for a method to determine the minimum distance which I can
route 1 GHz traces from other devices (including metal pin row headers)
without compromising the EMC performance (characteristic impedance) of the
traces, while preventing any common-mode coupling to the other devices.

Any formulas, suggestions, or ideas are appreciated.  Also, if anyone knows
of any EMC layout modelling software which addresses this issue, please let
me know.

Thank you,
