I have an example
of that on my page Unwin antennas where I specifically state the
rudiments of current flow. As yet nobody has supplied scientific data
to show that flow is otherwise. Thru out the ages it has been
understood that the datum line for the laws of physics is the state of
equilibrium such that all forces are accounted for. For radio this
requires the use of radiators of a full wavelength which supplies
equilibrium and resoinance. Yet for some reason many including Kraus
has rejected this undeniable fact, Thus when applying Maxwells
equations they can never attain 100 percent efficiency. This can ONLY
be attained when an array is resonant and in equilibrium as must be
the individual radiators that consist same. On top of that, there is
no reason that a radiator should be straight only that it is in a
state of equilibrium. snip

Art,

I think this paragraph may be one of the reasons for all the protests. It
isn't necessary to achieve 100% efficiency or to use a full wavelength
radiator in order to broadcast (or receive) a radio signal. It may be
desirable, but it isn't necessary. Modern equipment has sufficient power to
overcome the inefficiencies when transmitting and can hear signals well
below the noise floor when receiving. A 50% efficient antenna is fine for
most applications and perhaps 10% or less will do at a pinch.

The patent office floors are littered with designs for better, more
effective mousetraps, but that 99 cent (pence) bit of wood with a powerful
spring will kill mice just as dead. :-)

The particle wave duality of electromagnetic waves was settled back in the
1930's and further refinements have only gone on to prove that
electromagnetic waves act as both particles and waves depending on
circumstances and measurement. There is nothing wrong in considering the
generation of an electromagnetic wave using particles, so long as the end
results are in agreement with measurements taken using standard scientific
equipment.

If your antenna calculations show 100% power transfer to the antenna and
100% power radiated, then that should be capable of being substantiated by
standard measuring techniques in the near and far fields.

If your antenna only shows these readings when a similar receiving antenna
is used and attached to the measuring equipment (rather than a standard
dipole) then you have either invented an entirely new field of physics, or
the calculations are wrong.

I'm sure your compact antennas do perform better than others contained
within similar physical dimensions. A full wavelength resonant radiator must
theoretically be better than a fractional or loaded system. But proving that
it is worthwhile, better and more convenient to Joe Public is a much harder
sell. Your ideas about particles might be correct, but do they give a better
understanding and predictions of antenna behaviour than the currently
accepted theories? In order to succeed, I would suggest that your theory
would need to match all current observations but then go on to make some new
predictions about antennas which can be measured and verified. That is the
way that western science has progressed since the Greek philosophers tried
to explain the world around them. Some Asian cultures are allegedly more
amenable to accepting that some things in the world are just the way they
are and require less stringent proof. It allowed them to leapfrog the West
and make significant practical developments of everyday useful stuff without
worrying about how it all worked exactly. The only problem with this
approach is that if you hit a wall in development, it usually isn't clear
how to make further improvements or solve the problem except by trial and
error.

Keep up the good work.
