  • Abstract
    The exact fields generated by transient electric and magnetic dipoles in an infinite conducting medium are derived. Specialization to brief, approximately triangular pulses then brings out the salient practical features of such signals. The peak signals are attenuated as r^{-3} or r^{-4} rather than exponentially, and, in a practical sense, they travel very slowly (mean effective velocity about equal to sonic speed for a range of 1 km in sea water).
