Hi John,

In fact a larger disk will actually raise the launch angle - hardly a
satisfactory mirror analogy.


the "mirror" produces (half of the) photons that the

Photons? This is CecilBabble. Mirrors as "productive" sources of
photons demonstrates the failure of analogies.

Do you deny the photonic nature of radio waves?

Hi John,

This last question is standard CecilBaiting at which he is a master.

I've made a career in photonics, so you will have to go some distance
to start offering a case that comes remotely close to their cross
application. Barring that, why introduce concepts that don't advance
the topic? The following is hardly any clearer by clinging to poor
metaphors:

I just realized that the sentence you quoted s easily misinterpreted.
When I said "the "mirror" produces (half of the) photons that the
full dipole would have produced." I meant that half as many photons
are produced, compared to the full dipole antenna that produces the
same fields above the center line. I didn't mean that the mirror
produces half of the total photons that are radiated.
