N2  - When the outputs of a 3 phase AC generator are connected sequentially to the three dipole electrode pairs in the arrangement of figure 1, the outputs will combine in the ground to produce a rotating dipole source. For the electric and magnetic field quantities Er, E¢, Ez, Hr, Hø, Hz for a horizontal electric dipole embedded in a conductive medium (Banos, 1966), the combination of angular quantities in phase and electrode geometry for the three dipoles involves the relations [see full text for equation] where Q is the azimuth and w the transmitter angular frequency. Both (1) and (2) reduce to the result [see full text for equation].
