Abstract :
Some calculations are presented to show the nature of the transient ground wave radiated from an electric dipole which is situated over a spherical earth. The moment of the dipole is considered to vary with time in a linear manner. It is shown that the departure of the leading edge of the radiation field from a step function form is a consequence of diffraction and loss in the finitely conducting ground.
