I have a friend asking for waveguide information, in reference to the
proposed PCB layout on this url:

He asks the following;
........................................................................................
What I need is the time-delay between spark generation and sympathetic
spark occurrence,
which will depend on spacing D and relative dielectric constant of the board
material. Another way to ask is "what is the propagation velocity within
such a waveguide?", or "what is the wavelength of the EM energy within such
a
waveguide?".
There will be a LOWER "cutoff frequency" for such propagation, too. So the
sparks will have to be fast.
......................................................................................
I think he's looking for the math to lead him in the right direction.
Thanks, Mike
