Over the range of a few octaves, propagation delay on the other hand

Ostensibly, it should be equal to sqrt(LC) series L, shunt C.


Actually, Jim, I do expect it to have considerable frequency
dependence. I think you can find info about this in books that
address the design of travelling-wave tubes.

But...one must be very careful about describing exactly the experiment
or the conditions around a particular scenario. That's why I don't
have much interest in getting involved in this "discussion": it could
well be that much of the difference among all the claims and counter-
claims could be trivially resolved through better communication.

I don't think they're writing about real transmission lines, Tom. If
they were doing that, there would be no discussion because then it would
be too hard to understand.
