Oscillating Electron Beam potential between metal plates

Click For Summary
SUMMARY

The discussion centers on calculating the potential developed by an oscillating electron beam between two parallel metal plates, influenced by a time-varying magnetic field. Participants emphasize the importance of using retarded potentials and simulation software to model the electron's undulatory motion. The conversation highlights the need for clarity in experimental descriptions to facilitate accurate assistance. Key insights include the significance of charge distribution on the plates and the oscillation characteristics of the electron beam.

Take the case where the electron-beam is oscillating between two parallel metal plates, there will be alternating potential developed between the plates as metal tries to negate all external electric fields.
My query is,
(1) How to calculate the potential developed and possible way to simulate it ?

(2) Will the potential developed be significant ?

Where and why do you expect any oscillation?

It's an equation i have derived with time varying magnetic field. At this moment before journal publication i really can't say much but i have simulated the particle trace of electron on simulation software and it gave a perfect match. The electron traverses undulatory motion(like in an undulator) but in time varying magnetic field.
Please i need help with finding the potential developed by bunches of electrons, all in same phase oscillating up and down at same frequency(also moving forward but don't require that component) between the two ends of each metal plates !

Thanks For the reply btw
 
Fair enough, but your account, nor the pictures, allow anyone to construct the situation you are trying to describe. So help the helpers help you if you can :smile:

Retarded potentials should help, alternatively use the simulation software.

There is an electron beam shot between the two plates at some fixed point? The variable magnetic field is some external input? How does it vary in time, and does it vary in space? Why is there a charge on the metal plates? It is impossible to figure out what your experiment is if you don't describe it.

One can visualize the motion of electron like that of the dielectric material(which is basically electron mass in my case) oscillating between the two parallel plates at fixed frequency:

The kind of charge distribution in the plates will be like this due to induced electric field of the electrons:

The electrons are NOT touching the plates,
the magnetic field is varying only in time and is externally applied. Just consider the electron motion in undulator with the electrons oscillating between the metal plates(like an undulator with two side walls)

True, will try to be more expressive then :thumbup:.
