Abstract
A new approach to solving the direct problem of non-stationary electrodynamics in a complete formulation for a heterogeneous geological environment is proposed. The new formulation of Maxwell's equations makes it possible to write down the equations of the electromagnetic field for potentials in the form of a system of first-order hyperbolic type equations. Information about the spatial distribution of specific electrical conductivity in the geological environment is contained in the electromagnetic response – the reaction of the medium to external electromagnetic influence.
