Dear Mike,
I gave to Uwe two hints in German books to the topic skin effect. To find
the eqations or curves for the thickness of the conductive layer as a
functon of thickness (diameter) and frequency, You probably must search the
library of the next engineering school or technical university.

Hey, not fair. I can't read German if that is what this is.

Lieber Uwe, hier also meine Qellen:

- Eine Seite  aus dem Repetitorium in "Siemens Compüonents 22 ( 1984) Heft
5
- Fritz Vilbig: Lehrbuch der Hochfrequenztechnik, Vierte Auflage, Bd. 1,
Seite 149-150, Akademische Verlagsgesellschaft, Leipzig 1944.

Du mußt also wohl oder übel in einer wissenschaftlichen Bibliothek in den
Grundlagenwerken der Elektrotechnik und HF-Technik wühlen.

55,
Hans-Albrecht
