Radiation fields from a horizontal electric dipole in a semi-infinite conducting medium

The radiation fields of a horizontal electric dipole in a semi-infinite conducting medium are developed to yield a ground wave near the surface and a space wave above it. Previous work for points of observation slightly above the conducting medium is extended to the entire region by including the height of the observation point in the evaluation of the integral by the saddle point method. The effect of burying a horizontal electric dipole is to modify the field intensity by exp ( ), where is the depth of burial and is the skin depth of the medium. As approaches zero, the expressions for radiation fields are identical with those developed by Norton.
