EM FIELDS OF A PHASED LINE CURRENT OVER A CONDUCTING HALF-SPACE

A simple and explicit derivation is given for the electromagnetic fiel ds of a traveling current line source located over a layered conductin g half-space, Special attention is paid to the case of a homogeneous h all-space where analytical closed-form expressions can be obtained. Of some interest is the radiation of a vertically polarized radio ground wave which would not be present if the line source was uniform.
