Hi John,

So, proceeding along your avowed lines of Photons, one of several
questions:
Presuming 100W radiated, how many photons would that be so that we
can talk about them by halves.

Well, you couldn't be radiating 100 watts in both cases if the field
strength is the same above the center line, but half the field is
missing in one of the cases.

But regardless of the radiating structure, if 100 watts at 40 M is
being radiated, you are launching about 2*10^28 photons per second.

Yes, that is perhaps unfair, however it demonstrates how easily the
discussion can tumble for lack of quantifiables such as that original
offering of 100W.

Hence the stipulation that the field strength above the centerline
being constant, rather than the radiated power. I missed that we were
only talking about a case of radiating 100 watts.

Should we discuss how infinitesimal the energy is in a 40M photon?
(Easily accounts for why so many are needed for that same 100W.)

Not much to discuss. I don't do such calculations often, but I get
about 5*10^-27 joule per photon. What do you calculate their energy
to be?

No, I suppose not.

Do you have some point?

Want to get into the problems of diffraction with object lenses that
measure less than a wavelength of the photon?

Sure. That will take us back to how an elevated radial system gives a
different vertical pattern than an actual ground plane or a lossy
ground does. You go first.

Hard to escape, and makes a mess of describing mirrors too, especially
when they are skeletal approximations as well.

You have to start understanding mirrors, somewhere. Perhaps you
prefer a different starting point. There are several.

I can offer more thread-busters when it comes to photonics, but that
is a slam dunk. Get us rolling on one ace proposition, and I will get
back to you in a couple of hours.

I have no idea what you are saying with these two sentences.
