Permeability and Permittivity of Free space versus particules

  • Thread starter owlal85

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.
