Re: photons

Plead geriatric. For permeability read permittivity yes there would be
a
difference between the propagation of an electric field and a magnetic
field
due to the additional rotational components in the magnetic field that
modifies its propagation.

.... and those differenences might be related to:

1/r^2 and 1/r^3 ?
(don't answer that just repeat it to
yourself a few hundred times ) .:-)
You can verify it with magnet, thread,
comb, steel bolt, paper and meter stick.
No clocks required! :o)

Look at the curve between x = 1 and x = 10.
You are saying you believe there exist a way to confirm
the two curves exactly converge in real space as indicated

Maybe, I am trying to work out how this was plotted, is the y axis the
input
impedance to the dipole ? I have know downloaded the text to go with
the
plot and have a little more idea what it was actually describing so
after
studying it I may revue what I have written below if needed.

s
The x axis is distance in wave lengths. 30MHz would be 10 meters Eh?

But you know full well any matter you put into that region
to make the measurements will be a new interacting structure
behaving just as the source radiating structure


..
dr
yes
s

How do you know at x = 1/ 2pi that the curves actually
reverse their y axis trend ?
dr
How do you manage to separate the impedance's for the electric and
magnetic
fields?
the electric field will be on a slightly different vector to the
magnetic
field due to the mag. field curveture.

s
You take the sample with either a Faraday shielded loop or a short
electrostatic probe. (A direction finding antenna incorporates both
types to resolve the 0 / 180 degree ambiguity of a loop antenna. )

s
We don't have to invent virtual spinning entities in space
if they, in reality they continue toward y = o and y = infinity
respectively


..
Yes that seems resonable but I think that the graph would be more
informative if the mag. field tracked out at for example a 1000Z's and
the
elec. feild tracked out at 100Z's for example although I cant think at
this
moment how to measure them.
s
Perhaps the sampling technique above makes it clearer.
d
4pi*10E-7 H mE-1 seems the calculation to find the mag. track out and
8.854*10e-12 F mE-1 for the electric field track out but I cant think
of how
to convert them into impedences at the moment so they could be applied
to
your graph.

Plenty of examples here:
