Lateral Electromagnetic Pulses Generated on a Plane Boundary between Dielectrics by Vertical and Horizontal Dipole Sources with Gaussian Pulse Excitation

Abstract

The exact lateral electromagnetic pulse generated by a vertical dipole excited by a Gaussian pulse is derived. A comparison with the previously derived approximate formula shows that the latter gives the correct field at all radial distances except for the nonappearance of the relatively small second pulse. Corresponding approximate formulas are derived for the electric field of a horizontal dipole. These should give the correct field except for the nonappearance of the small second pulse in some components.
