Approximate solution of an inverse scattering problem for a plane dielectric structure with perfectly conducting base

An approach is proposed for the approximate solution of an inverse scattering problem for the plane electromagnetic wave incidence on a plane layered dielectric with a perfectly conducting substrate at the base. It is shown that this inverse scattering problem is identical to the inverse scattering problem for a purely dielectric layered structure when the values of impulse response on a limited interval are taken as initial data. This interval corresponds to the time of plane wave propagation in dielectric media without interaction with a perfectly conducting substrate. The parameters of approximation models of the impulse response are determined by methods of spectral analysis from the values of the reflection coefficient given in a limited frequency range.
