Maxwell published and his equations have been successfully used ever
since.

My ARRL Antenna Book says in its chapter on "Computer Programs":
"The availability of computers in the 1960s provided antenna designers
with an alternative. They could develop software to simulate the
performance of antennas. In general, these techniques either numerically
solve Maxwell`s equations by discretizing the problem using intergral
techniques such as Moment Methods (MOM) as discussed in Sec. 14-11, or
differential techniques such as finite elements or finite
difference-time domain."

Is the "Antenna Book" bull too?

O.K. you win. Maxwell never did add the correction factor later to be
known as the displacement factor.
It is not known how that addition came about as Gauss Faraday and
others never included it in their findings
It is known however, that the name assigned to this addition was by
Maxwell while others were watching T.V.
Obviously somebody had sneaked in an addition to the supplied data
while others were engrossed on the T.V.
as the football game was ongoing.
Maxwell and computer programs were not mentioned at that time nor was
the ARRL handbook, these came about much later
where the antenna was viewed as a vanishingly thin radiator where the
inside diameter was too small to non existent because of the skin
depth that met each other from both side thus cutting of passage of
anything from the top of a radiator.
Because of the reflection created by the thin radiator the current
refersed direction and travelled down much faster as the circular
fiels
now aided the flow of current instead of resisting it like it did on
the upward direction. Richard, right on. You have got it right without
a doubt. I am now convinced. Presumably you are happy now you have
been vindicated and can now put your pen and pencil down.
