All necessary resarch are done by radio people. You all know how antennas
work. Monopole and dipole means the electric pole because no magnetic
poles.
You only do not realize that EM waves can start from the ELECRIC field.
The
electric field is radiated from the ends where is high voltage and no
current.

These guys are not helping you! What they are doing is using you for
cannon fodder.
Day after day they state the new for me aguments that the acoustic analogy
is the winner.
Try looking at things my way. You know that when a time varying
current is applied to a radiator that it also supports a reacting
current with spin, known as as an Eddy current
You also know that the current applied produces a electrical field and
a magnetic field that interchange energy between each other in the
form of a tank circuit.
You go into details. Now is not time for that. Now we should work out the
consensus on which part of the radiator radiate the radio waves.
Now look at the sequence of actions.We do know that the Eddy current
produces a lifting force and a spin force and we also know that there
is a electro static field surrounding the radiator. First we must
recognise that particles encapsulate the whole radiator but can be
individually lifted from the radiator with spin applied a short
distance. At this point it enters the electrostatic field around the
radiator where at the same time the generated magnetic field is
intersecting the electrostatic field. The moment that the lifted
particle enters the electro static field mix it is subjected to a
accelarating force exactly the same way as a electron in a CRT is
impacted upon. If you refer to the actions within a electron tube you
will note that the electrostatic field offsets the direction of the
accellerated particle into an exiting parabolic direction. The
combined fields will only accelerate the particle while it is within
the electrostatic field proper, after which it has a straight line
projection with spin. The time that it is within the electrostatic
field is the total accelerating time ie Newtons law 1/2 ft sqd.
The acceleration imparted to the particle happens to be the speed of
light which implies that this particle is able to emit light. If you
have difficulty then read up on the CRT.
As a point of interest the Eddy current itself must be balanced by an
equal and opposite force per Newton and if we look at it in boundary
terms we see that the opposing force is the combination of Gravity and
the rotation of the Earth. What this shows is that the particle has
spin and accelleration where the vector associated with Gravity is now
neutralized such that it retains its straight line action with spin
as it traverses the boundaries of the Earth Another thing of
importance is that Newtons laws are based on the condition of mass
where the particle becomes an excellent fit as opposed to a field or a
wave.
Back to the radiator itself. If it is a full wave length then it is a
closed circuit of the tank circuit form. If a radiator is less than a
wave length then yes, charges will form at the end of a radiator but
is hampered from further movement by the opposing impedance of the
environment. The charges will still leak but with out a spinning
action it will remain in the near field. Ofcourse changing the
environment will give an instantaneus charge in a spark form because
as an open circuit it always searches for the closed circuit function.
It will not be easy to work out here all details.
