The transient electromagnetic field from an antenna near the plane boundary between two dielectric halfspaces

Summary In a preceding publication of the present author expressions were derived to describe the pulse field from a vertical electric antenna placed near the plane boundary of two semi-infinite diëlectrics. These expressions appeared to be integrals on a finite range in the complex plane and were derived for the field in both media. The analysis of the field also gave information about the time of arrival of the several pulse-fronts.In the present paper the field is studied in more detail, and with the aid of suitable approximations more specific results are obtained, such as logarithmic field singularities.Also a discussion of the pulse analogon to the Zenneck wave in the time harmonic case has been included.
