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.
