How Energy States Appear in an Antenna (Idea)

I’ve been considering theHere’s a possible quantum mechanical descriptionview of how antennas and wanted to share my thoughts, though I'm not entirely sure about it and would appreciate feedback.

It seems to me that electrons in the antenna can't form a coherent state like bosons because they are fermions, and thus they obey the Pauli exclusion principlework, which means they can’t occupy the same statefocusing on plasmon modes. Instead, I think the way it worksThis is like thisjust a developing idea:

  1. WhenCollective Electron Behavior:
    Electrons in the antenna form the Fermi sea and can’t occupy the same state due to the Pauli exclusion principle. Instead, they oscillate collectively in response to an oscillatingapplied voltage is.

  2. Oscillating Potential:
    The applied, it voltage creates a standing wave alongstanding wave that perturbs the antenna. This standing wave essentially acts like a harmonic oscillator potential forelectron cloud, exciting plasmon modes—quantized collective oscillations of the conduction electrons.

  3. Electrons, being quasi-free, can occupyPlasmon Modes as Energy States:
    These plasmon modes act as the quantum mechanical energy levels created by this potentialof the system. They are excited by the standing wave and can transition between these levelsdecay by emitting photons.

  4. Photon Emission:
    Radiation occurs when plasmon modes decay, coupling to the electromagnetic field and emitemitting photons during these. The coherence comes from the collective oscillation, not individual electron transitions.

I think the coherence comes from the collective oscillations of the electrons in response to the applied voltage, not from the electrons themselves forming a coherent state. This is why we get photon emission—due to the transitions between energy levels in this modulated potential.

I wanted to clarify this since I had the same question, and I really want to understand it better. It’s quite important to grasp the nature of how quantum mechanics applies to antennas.
