THE TRANSIENT FIELDS OF DIPOLE ANTENNAS IN THE PRESENCE OF A DIELECTRIC HALF-SPACE

Abstract

The transient fields produced by vertical and horizontal electric dipoles with impulsive current excitation in the presence of a half-space are considered. For special source and observer configurations, exact, closed form expressions for the fields produced by impulsively excited dipoles above a nondispersive half-space are given. For the dispersive case, estimates of the transient fields from asymptotic approximations are given. A knowledge of the interactions of dipole antennas and a half-space is useful for studies of the background return from the half-space and for studies of the scattering by small targets on or near the half-space.
