It was also done calculation of changing wave form with its finite amplitude and its reflection from interface taking into account and absorption coefficient and dissipation frequency dependence in the second medium. It was proposed the method of numerical solving of the scattering direct problem in terms of the equations such as Lippman-Shwinger equation co-ordinate space and in the space of space frequencies Fourier allowing fast and relatively easy to solve such problems that necessary for inverse problem solving.
