### Abstract

Electric and magnetic fields below the horizontal surface of a conducting structure have been derived in terms of the subsurface currents. The formulae obtained are valid for any subsurface electromagnetic problem, e.g. for sea-bottom magnetotellurics or mining electromagnetics. The simplifications of these general three-dimensional formulae to one-dimensional and to the basic two-dimensional situations yield a clear physical meaning to the depth-dependence of the impedance and consequently to the apparent resistivity and the phase. -from Authors
