That is the presently accepted formula in science where atoms are
removed from the matrics of the radiator.
For me, all diamagnetic materials are completely covered with
particles that entered the solar stream from the Sun. As soon as they
are projected away from a radiator another takes its place, thus no
changes in mass.

what about my ferromagnetic radiators??? since they don't have your magical
levitating diamagnetic neutrinos they must constantly be losing mass and
will eventually fall apart!

You have made a small mistake. Antennas are feed with the oscillating

longitudinal wave.

No, you've made a mistake ... again. EM waves are transverse waves in
air (i.e. around a normal antenna) not longitudinal waves (see
http://en.wikipedia.org/wiki/Longitudinal_wave).

EM waves by Maxwell are transverse waves. They are the paper waves. The
real electric waves are mainly longitudinal.

* Would you care to cite a reference where it is stated that EM waves in the
far field of a transmitting antenna contain a significant longitudinal
component? Many respected authors, such as Kraus, have illustrated the
contrary, but their work isn't limited to paper; people like Kraus have
designed real antennas of types that are still in use today.


Sound waves are longitudinal because air pressure is a scalar, whereas
electric and magnetic fields are vectors - they have polarisation.

The math has not to do here.

* What 'math'? ... just the mention of scalars and vectors, in a group
devoted to antennas. Please.


Here is the full acoustic analogy. The two loudspeakers work like the two
monopoles.

* Rubbish. What 'two loudspeakers'? Ever heard of a horn loudspeaker? ...
it produces longitudinal pressure waves.


Also, antennas that radiate are fed with alternating current. The
terminal voltage is almost immaterial in comparison with the current -
that's what causes the radiation.

If you want to discover what radiates I suggest you read one of the
normal text books on the subject, like Kraus 'Antennas', and stop making
up your own versions!

To discower what radiates will be better to do experiments with tipping of
monopole antenas.

. . .

EM waves in an unbounded medium, far enough from a source to be in the
far field, have a longitudinal component only if the medium has loss. In
air, the fields are for all practical purposes purely transverse as
christofire says. Hence the descriptive name for the field orientation
as TEM for Transverse Electro-Magnetic. This is also true of some
bounded media such as coaxial cables, where again the fields are
transverse except for a usually small longitudinal component caused by
loss. But in other bounded media such as waveguides, one field or the
other (electric field in TM mode and magnetic in TE mode) can be
longitudinal. You'll also see a longitudinal component when a wave gets
close to lossy ground, although it's typically not large compared to the
total field.

Photons are quantized elementary particles in the standard
model. Every time you see something, like this posting of mine,
you are capturing the photons incident upon your retina.

Double slit experiments with photons have been performed
with a single photon which apparently can go through both
slits at the same time and interfere with itself on the
other side. Those photon detectors indeed can capture
individual photons.

Photons are quite often generated and detected within
particle accelerators.

My problem is with how photons fit in with radiation?
It is a nice name but how does it get launched and where did it come
from?
Personaly I can't distinguish it from a particle at rest on a radiator
or how it can possibly get attached to it which apparently you
believe. I just want to see how this proton fits in with what we know.
Waves or particles.

Chris, what I believe he is referring to is that computer programs
support a tipped vertical over one at right angles to earth. Computer
programs are supposed to be based on Maxwell's formula. Is this an
error and how do we fix it. If it is not an error then it supports the
presence of the Coriolis force in collusion with gravity. and not
gravity alone.
More to the point, it is common knoweledge that there is no full
understanding of radiation
available anywhere. Thus he is asking probing questions to fill in the
gaps.
Personaly I am not willing yet to say antenna programs are at fault
until more explanations come about. Can you explain what he is

where do you put in the Coriolis effect or gravity direction in your
computer modeling program? i haven't seen one yet that let you put those
in, or even the latittude that could be used to derive the effect from.
without those you are just tipsy.

My own take on the effect of tilting a vertical antenna is that if its
length is an appreciable fraction of a wavelength then tilting it will
distort its radiation pattern and will upset the uniformity of its
polarisation, which will impose a further effective radiation pattern. If
this results in a bit of gain in one particular direction with respect to a
particular polarisation then fine, and this may be of some use in amateur
radio service although it isn't how vertical monopoles are most often used
(i.e. their omni-directional pattern is their strength and there are many
other, better ways, to obtain directional patterns).

However, the theory on which all the well-known modelling programs is based
is the simple stuff described by Kraus, et al, and probably in most cases
follows from the original work that led to NEC

It is conceivable that the Coriolis effect may act upon EM radiation.
But given the speed of propagation of the radiowaves the effect would
truly be miniscule. I Art thinks the rotation of the earth has any
significant effect on EM propagation he should show some reference. Im
not going to hold my breath until that happens.
