Conclusions,s been illustrated also by some original simple descriptions. Besides this we have reported criticisms of description of light propagation in a nonlinear medium using a spatial variable instead of and similarly as the quantum-mechanical time parameter.

Macroscopic Theories and Their Applications,tic field at least in the one-dimensional case. A complete analysis could be provided only for the parametric processes, in which the momentum operator is effectively quadratic. It has been noted that the nonlinearity of the process may lead up to a need of a renormalization. Nevertheless, there is

Microscopic Theories,pproach the electric permittivity of the medium can be derived. The description of the fields can be quantized. It seems that the separation of the equations for the medium polarization is not a sufficient ground for the theory to be considered microscopic, but we adopt this nomenclature. It is impo

Periodic and Disordered Media, concepts of periodic and disordered media depend on whether electrons or photons are investigated. Nevertheless there is an analogy between the wave function of a single electron and the classical electromagnetic field. Therefore it was possible to achieve many results for periodic and disordered m
