Default Equilibrium and Ham examinations

In direct terms I have stated that current flows down the
center
of a radiator if it is of a fractional wave length. A very simple
statement which nobody wishes to address. Fine by me, the thread would
then have a single posting and the multitude can generate questions
and discussion about deep space or other topics of choice.


Severns, QEX, Nov/Dec 2000, pp 20-29 does address the issue.
On page 22: "At some points within the wire, the instantaneous current is
actually flowing backwards (minus signs) due to the self-induced
eddy currents that are the underlying phenomena responsible for skin
effect."
These results were verified with Ansoft's "Maxwell" FEM software.
An excellent treatment of the math can be found at:
