WebbThe field in the dielectric is considered to be nonuniform because of the space charges created by collision ionization, and the enhanced field adjacent to the cathode causes … WebbThe Lorentz classical theory (1878) is based on the classical theory of interaction between light and matter and is used to describe frequency dependent polariza- tion due to bound charge. The bindings between elec- trons and nucleus are supposed to be similar to the that of a mass-spring system.
