“…Results of the numerical study in the problem of low-frequency sounding of the Earth crust [3] have demonstrated serious limitations of such approach for large perturbations, when the Born approximation (first guess of iterative method) is inapplicable. To overcome these restrictions of perturbation theory, the new method of dual regularization based on the Lagrange approach in the optimization theory [4] has been applied [5] in this problem. Results show its ability to retrieve very strong variations of conductivity profiles.…”

The dual regularization method is applied in the inverse problem of electromagnetic scattering to retrieve permittivity inhomogeneities in multilayer periodic dielectric structures. Based on the developed theory, the solution algorithm has been worked out and applied in the numerical simulation of the multifrequency reflectometry diagnostics of inhomogeneities in multilayer structures of X-ray optics.
