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: http://www.g3ynh.info/zdocs/comps/zint.html Frank |
