The Electromagnetic Field of a Unit Vertical Electric Dipole in the Presence of a Plane Boundary, terms of general integrals for many years. Following Sommerfeld, it has been expressed in terms of derivatives of the Hertz potential. In this form it is difficult to visualize the nature of the electromagnetic field. A somewhat better insight is obtained from the explicit integrals for the compone

The Electromagnetic Field of a Horizontal Electric Dipole in the Presence of a Plane Boundary,range of frequencies used in broadcast radio communication. Antenna lengths of a quarter- or half-wavelength in air are practical and directional arrays are readily constructed. The entire far field along the surface of the earth or sea is a lateral wave often called the Norton surface wave. At lowe
