The coherent RF energy flows near the surface of the conductor at the speed
of light in clouds of photons. Given the magnitude of the Poynting vector,
we can calculate the number of photons passing through that area in unit
time. Those coherent photons that extend into the inner surface effect area
have the highest probability of their energy being converted into infrared
higher energy photons, i.e. heat radiation. After all, RF photons cannot
exist for long deep inside a real-world conductor and they cannot exist at
all inside a zero resistance conductor. Here's a question for you: How many
10 MHz photons does it take to generate one infrared photon?


Only steady-state DC doesn't involve photons. All AC, RF, and transient DC
functions involve photons and that has been accepted as scientific fact for
about a century. Unfortunately, the physicists being quoted by you were
completely ignorant of the existence of photons.


Could you please to quote the physicists which are completely sure of the
existence of photons?
