And you tell us that radiation from monopoles antennas is polarised.
There was a topic polarisation. In wave area is term alignment when we
have the two sources. Aligment of "dipoles" not means that waves are
"transverse".
In the reality no transverse waves. Waves appear in compressible medium.
All waves are the "pressure" waves. In math you can assume
incompressibility. But we here NO.

So, pray tell, explain the physics of a vertically polarized pressure
wave.

One wave is not polarised. The two pressure waves from the two sources
interfere. See "Directivity and phasing".

You obviously know what's going on here, and I do not. Please educate
me.

"This fourth edition blends, in Joseph J. Carr's words, "the theoretical
concepts that the engineers and others need to design practical antennas,
and the hard-learned practical lessons derived from actually building and
using antennas -real antennas, and the hard-earned practical lessons
derived from actually building and using antennas - real antennas made of
real metal - not merely theoretical constructs on a blackboard."

Now is the electronic era. Electronic is from electrons. They are
compressible and have the inertia. You all construct antennas where
electrons build up voltage. But on the blackboard are math for
incompressible fluid.

no it isn't. you are obviously way out of date. stop looking way in the
past for theories that were obviously disproven decades ago and look at
modern texts to see which ones have survived 100+ years of experimental
evidence.

Look at the famous equations - there no voltage at all (only current).

in any electronic system you really only need voltage OR current, they are
always related by the impedance. So if you read modern texts you will often
see that they derive equations in either voltage or current form then show
the other form for reference, or sometimes leave it as an excercise for the
student.

If somebody do math for electrons then such math will be on the
blackboards.
But it is not necessary. The beautifull EM equations are the same like for
fluid mechanics. They will be saved. Radio engineers do not use them and
can wait for the proper ones the next centuries.

no, real engineers are trying to educate people like you who are stuck in
the past with outdated theories and simplified misconceptions... or we could
just ignore you and hope you go away quickly. personally i think it is more
fun to watch what comes out of the mouths of babes when you tickle their
feet.
