Abstract: In this paper, the theories of vertical return stroke, in which Bruce and Golde [1] current is supposed to flow, have been extended to oblique orientations of the channel. The VLF electric field and power density have been calculated for a distance 100 km from the source as function of the channel parameters and of the channel orientation. It is shown that VLF electromagnetic energy radiated from the oblique channel is of Gaussian shape with the maximum appearing at certain frequency depends on orientation of channel.
