RE: NEC-LIST: Zero-Q antenna

Dear Colleagues,

Unfortunately the Grimes & Grimes papers are filed with misconceptions and
errors that lead them to invalid results. For those who are interested I
refer you to an excellent paper by Prof. Robert E. Collin on "Minimum Q of
Small Antennas," Journal of Electromagnetic Waves and Applications, Vol. 12,
1369-1393, 1998.

Quote: An ensemble of four dipoles, two electric and two magnetic ones, one
of each type lying along each of the x- and y-axes. More details are said
to be in the 2000 paper in MOT Letters. They say there is strong intermodal
coupling between the x-directed electric moment and the y-directed magnetic
moment, and vice versa (I think that's questionable).

I haven't; sorry; but I wish, and I bet others do, too, that you
would post a summary of what it is and how it works, to the list.

Tnx -chuck.
