MAGNETIC COMPONENTS RADIATED BY A HORIZONTAL DIPOLE AT VLF.
Abstract
The electromagnetic radiation characteristics of a horizontal vlf antenna near a semi-infinite conducting plane along its perpendicular bisector were examined. An expression was developed for the electromotive forces induced in vertical loop antennas by the surface and downcoming sky waves along the perpendicular bisector. A simple expression for the ratio of these emf's involves the ground distance from transmitter to receivers, the angle of incidence of the wave on the ionosphere, and the ionospheric reflection coefficient. The effects of nonhomogeneous ground conductivity were also examined and were found to influence the magnitude of the ratio of surfacewave field to sky-wave field. (Author)
