A full wave approach is used as the basis for determining the transient electromagnetic field response from nonparallel stratified models of the earth's crust. The full wave analysis which satisfies the reciprocity relationships in electromagnetic theory accounts for the scattered radiation fields (considered in Part 1) as well as the scattered surface waves (considered in Part 2). These investigations are relevant to electromagnetic probing in geophysics (active remote sensing) and to problems of communications and navigation using pulsed radio signals. Thus, in this work analytical expressions are derived for the propagation delays and distortions due to nonuniform ground effects. Both analytical and Fast Fourier Transform techniques are used to obtain the solutions.
