You assume that there no field electron emission. Why?

Please don't tell me what I am assuming because you are invariably wrong. As I (and Richard Feynman) have told you before, the fields emitted by electrons consist of photons. Electrons escaping a transmitting antenna are a non-coherent corona discharge. Photons escaping a transmitting antenna are coherent RF energy.

Back in the early 20th century when spark gap transmitters were being used, the spark gap function, like lightning, generated non-coherent photons which filled the RF spectrum. Nowadays, a CW signal is mostly coherent with a small amount of non-coherence associated with the transient rise and fall times.
