Abstract
A dual regularization method to retrieve subsurface Earths crust conductivity profiles by ultra-low frequency (ULF) spectral measurement data has been proposed. In this method, the corresponding inverse problem is solved in its initial differential statement on the basis of the theory of optimization and optimal control without the reduction of Maxwells equations to non-linear integral equations, as it was done before.
