Frank,
I tried to access your bookmark and was parked at their homepage only.
How do you access the search function or go inside?

Subject: Re: [TCML] Skin effect
Hi Christopher,
You might consider looking at 1920's medical papers as well. They
used spark gap Tesla and D'Arsonval machines for surgery.
In some of the Fischer Diathermy manuals of that period they always
suggested the Doctor practice on pieces of meat before using it on a patient!
They showed photographs of the desiccation of tissue with different
shaped objects.
There is a spark gap machine still widely used today called a Bovie.
There are modern machines still in use for this same purpose and if
you could contact the vendors they might shed some light on the
best frequencies for different applications. One such machine is
called a hyfrecator and is used to remove surface growths and etc.
An on line source to view the older manuals is:

Hi Christopher,
I'm with Gary in that I commend you for looking at this. I also
agree with Jim Lux that there are vast papers on the subject, but
not all those papers are easily accessed for the general public.
Most skin effect papers will deal with RF cabling and pcb
engineering. But regarding human body skin depth, affects at F
with X current, well, I don't know how much is actually written
about (possibly several papers). It would be an interesting study.
I also look forward to what you can bring to light.

Hello, everybody,
I've been reading up on the skin effect, and there's nothing
that's very conclusive on it. I have seen arguments that go
either way, but no actual studies. I'm in the process of testing
this. If you'd like to read about my test set-up, and, possibly,
donate to the cause, you may go to my website at
http://www.teslasurplus.3000farad.com/donations/donations.htm
I am in need of a microscope and capacitors, as described on the
page, and I was wondering if anybody knew of a way to acquire
said items. I haven't been able to find any microscopes powerful
enough for under $100 to test the burning of the tissue.
I was wondering if anybody knew of any group that had tested the
skin effect on biological conductors.
The theory for the skin effect is simple, but it is hard to
understand exactly what forces are to blame. It's also difficult
to determine what amperage is enough to cause RF burns over extended periods.
