Abstract :
Simple, closed form formulas are derived for the transient response between dipoles at arbitrary locations above a dissipative earth. Both early time and late time responses are displayed. The case of an homogeneous earth is treated, using a single image for early times and an additional set of continuous images for late times. The results are checked favorably against published work. Multiple images are used for the case of a two-layered earth.
