Abstract:

The theoretical problem of predicting the effect of the propagation medium on the form or shape of the low frequency electromagnetic pulse of nuclear origin has been discussed in a previous paper. This paper presents some greater detail on this remarkable propagation phenomenon. Particular emphasis is placed on the construction of transforms amplitude and phase of the propagation medium as a function of frequency which can be employed to propagate theoretically almost any pulse shape. The distinctive features of the propagated pulse at great distance from the source can be identified with particular reflection regions of the ground and the ionosphere along the path between the source and the observer.
