Problem of diffraction on nonlinear dielectric layered structure. Generation of the third harmonic

The problem of diffraction of a plane electromagnetic wave on transverse non-homogeneous, isotropic, not magnetic, linearly polarized, nonlinear dielectric layer (Kerr-like nonlinearity) in resonant area of frequencies is considered. The analysis of a problem of diffraction on nonlinear layer taking into account the multiple frequencies generated in considered open nonlinear structure is carried out.
