Abstract

The exact solution for the electric dipole is obtained for the case where the ground plane, of infinite extent, is characterized by surface impedances which are different in two orthogonal directions. The integral representations for the transverse magnetic (TM) and the converted transverse electric (TE) fields are evaluated by two asymptotic methods which have overlapping regions of validity. A simple expression is obtained for the ratio of the TE and TM fields produced by the vertical dipole when it is on the surface
