Direct Time Domain Calculation of Near Field of Dipole Antenna in the Presence of a Half-Space

The paper deals with a direct time domain calculation of the electric field in the close vicinity of dipole antenna radiating above a half-space. Formulation is based on the space-time dependent Hallen integral equation, while the electric field is obtained from the corresponding integral formulas. The numerical procedures stem from boundary element formalism. Some illustrative numerical results pertaining to the case of perfectly conducting (PEC) ground and dielectric half-space, respectively, are given in the paper
