Abstract We considered direct problem of pulsed electrical prospecting, which is based on approximation model of a polarizable electrically conductive plate (plane S), according to well-known Cole-Cole polarization model. Vertical electric lines are used as a source and receiver of a pulsed electromagnetic field, which are relatively new receiving and generating devices in pulsed electrical prospecting and fairly easy implemented in marine search and mapping of oil and gas deposits, deposits of non-ferrous metals and other mineral and raw materials sources, especially in hard-to-reach and / or deep water areas of the World Ocean, e.g. under the ice of the North Arctic ocean, in Russian exploration areas, in rift valley of Mid-Atlantic ridge. We developed analytical model of unsteady electromagnetic field of polarized plane S, excited by a vertical electric dipole. According to the Pearson hypothesis and numerous experimental data, obtained by different researchers, the polarizability of the plate is a relatively new indicator of the oil and gas deposit, which is identified by EMF induction sign change. To increase the depth of the study, we present an analytical model of integral characteristics of the pulsed electromagnetic field of polarized plate, excited by a vertical electric dipole. In this case, the magnetic flux induction, as well as EMF, changes charge.
