The corresponding particles are called "virtual photons". Outside the conductor but at large distances from the antennae, the energy and momentum is carried by "radio waves." The corresponding particles are called "real photons." Inside the conductor, energy and momentum is carried by collective excitations such as plasmons, phonons and polaritons. These collective excitations formed from photons, electrons, and the vibrations of nucleii. These collective excitations are also quantized, and can be considered particles. However, they are not considered fundamental in the way that electrons and photons are fundamental.

There are rather easy rules of thumb that connect classical electrodynamics (CED) to quantum electrodynamics (QED). <LOL>

What type of engineer were you? You clearly don't know classical physics. Otherwise, you would recognize what a multipole electric field is. Or even a multipole magnetic field. We are not talking quantum mechanics here. I am not even talking about relativity. I am talking about classical antennae theory. Honest, Einstein had nothing to do with classical antennae theory. It was developed way before him. I am sure that Excognito knows about dipole antennae, monopole antennae, etc. He knows about radio waves, harmonic frequencies, fundamental frequencies, etc. How much electrical engineering do you know?
