No but it could be calculated out of a real world struture a I have
done
Why are you having a problem with this I thought that the difference in

attenuation between E fields and mag fields should be ample evidence
for
treating them separately if convenient. ??.

Magnetic fields are produced by moving electric fields so there
is difficult to treat them separatley.
dr
What would you say was produced by a very high impedence source into a high
impedence dipole in a large area of vacuum.????? How much in proportion to
Electric to Magnetic do you think we get in the radiation from some far
Galaxy???
>From your link 'Electric fields form lines which are trajectories along
which a very small free charge would travel in the absence of a Magnetic
field in the same place' What happens when the magnetic fields disapear at
1/r^3 to the electric fields that are still cracking along at 1/r^2. Do they
crash into the magic magnetic buffers ??
s
Better you should first consider two Faraday shielded loops.
Here the Coulomb coupling can be canceld both in the equations
and in practice. It is not terribly efficient but you can learn much
from it.
dr
Yes about magnetic fields but probably nothing about Electric fields??. I
will add my interpretation of magnetic fields to a page on this subject soon
I think that trying to understand the modulation before the carrier of a
radio transmission via the radiation could well leave you confused.
