Permeability and Permittivity of Free space versus particules

Click For Summary
SUMMARY

The discussion centers on the fundamental properties of permittivity (€0) and permeability (µ0) of free space, and their relationship with individual particles such as electrons, protons, and neutrons. It is established that these properties are defined for continuous media, and thus do not apply to standalone particles. The conversation also explores theoretical models where permittivity and permeability could be adjusted for particles, suggesting that such models would require maintaining a constant impedance (Z) while decreasing the speed of light (c) in the context of electromagnetic waves interacting with particles.

PREREQUISITES
  • Understanding of electromagnetic theory, specifically permittivity and permeability.
  • Familiarity with particle physics, including the properties of electrons, protons, and neutrons.
  • Knowledge of continuous media versus discrete particle models in physics.
  • Basic grasp of electromagnetic wave behavior and impedance concepts.
NEXT STEPS
  • Research the mathematical models of permittivity and permeability in continuous media.
  • Explore the implications of particle physics on electromagnetic theory.
  • Investigate the concept of impedance in electromagnetic wave propagation.
  • Study the behavior of electromagnetic waves in non-continuous media.
USEFUL FOR

Physicists, electrical engineers, and students studying electromagnetic theory and particle physics will benefit from this discussion, particularly those interested in the theoretical implications of particle properties on electromagnetic behavior.

We know for sure €0 and µ0 for free space.
We know as well €r and µr for material
Have theses values been calculated for stand alone particles like an electron, a proton or a neutron?
Have somebody then connected theses values to an atom (of hydrogen for example) which is a combination of moving particules an free space ?

Can anybody help?

Permittivity and permeability are properties of continuous media. A single atom is not a continuous medium. What you want doesn't exist.
 
No one knows what an electron is, let alone any material properties. I've seen people try to assign a higher permittivity to a sphere as a model. If I were to try such a model, I'd increase both permittivity and permeability proportionately so that Z is constant and c decreases. You could then view particles as local increases in space "density". In fact, it would be interesting to derive the radial dependency required to make an em wave "orbit" such a sphere.
