Skin Effect, anyone can help?

[sinatra]

Hello People.

First, I have to say that I'm very happy with the return of this GREAT forun!

I need some help about Skin Effect.

Does anyone have experience or some good hints about how to compensate Skin Efect on coaxial cables?

Some parameters (those are real values :') ):
Rise time ~ 200ps
Pulse duration ~ < 1ns
Lenght ~ 100m
type rg58 (50ohms)
Currents ~ tenths of KA
Voltages ~ tenths of KV

Some article or design experience may help.
Thanks a lot to all you.
S.

Ps: Again, Elektroda, great return!

He has a weekly newsletter, he would love to answer your question.
I'm sure he has in the past, check out his database.
It takes light from your nose to reach your eyes about 100 picoseconds!
Thats what you call, "The Skin Effect!"

Looks like your question is more from pulsed power domain. you are trying to build some kind of 50 ohm pulse forming network. I'm not even sure the work skin effect has the meaning for your case. Try to look in the book like basics of UWB radar technology, or some other pulsed power book. This is one of the typical PFN (pulse forming network) issues you are discussing
