The Third Electromagnetic Constant of an Isotropic Medium
... In principle, the best way to discuss electromagnetic processes taking place within a material medium is to use the subatomic picture in which matter is but a huge number of fundamental particles crowded in the vacuum. The charges and currents of these particles can be fed into the equations of vacu ...
