Generation and resonance scattering of waves on cubically polarisable nonlinear dielectric layer

The analysis of the scattering problem and the generation of the third harmonic by excitation by a plane wave passing a non-linear, isotropic, cubically polarisable, non-magnetic, linearly polarised (E polarisation), layered dielectric structure is carried out. Results of the numerical investigation of both the values of the non-linear dielectric constants corresponding to given amplitude of the incident field and of the scattered and generated fields are presented.
