In textbooks are prsented all theories and hipothesis.
It is your choose which one do you prefer: EM, photons or like sound.

"Like sound " antennas are in sale for ages.

If Art's are or will be - I do not know. I am not an expert. (I have
trouble
with understanding Art's idea - he is using very sophistcated terms).
S*
show me the equations for modeling a dipole radiation pattern using


sound in free space, be sure to account for polarization.


I have something like

Transversal wves have no sense. The equations are usefull for teaching
the

math.


right, read this carefully from that 1864 note: 'the requirements of

his mechanical model keep him from finding the correct boundary
conditions, so he never does this calculation'.

This is just one of

the basic shortcomings of using a mechanical analogy, you can not
satisfy the electric and magnetic field boundary conditions that the
final version of his equations handle properly.

In science area are scientists and teachers.
All scientists know that electricity, magnetism and gravity are the same.
Teachers know that the three must be taught seperately. Are you a student?

while some basic

effects like the interference patterns can be duplicated for both
longitudinal and transverse waves, they are not interchangeable in all
cases and trying to do so will only lead to absurd things like
electrons jumping off antennas or the need for an aether to transmit
em waves.

Maxwell's model is for the aether. But with the two substances: magnetism
and electricity.

Your antennas have the blunt tips to prevent the "jumping off ".
The alternate voltage in the ends create the oscilation of electrons in
neighbourhood .

Electrons in space are detected. So they are the aether.
Do not you hear on Dirac electron see?
