THE ELECTROMAGNETIC FIELDS PRODUCED BY A GENERAL CURRENT DISTRIBUTION IN A CONDUCTIVE ENVIRONMENT UNDER CERTAIN SYMMETRY CONDITIONS.
Abstract
The detonation of a nuclear weapon near the surface of the ground generates large electromagnetic fields. The distributed current and time and space varying conductivity caused by the detonation make analytic solutions to Maxwell's equations intractable. A numerical technique is presented which allows one to find the nuclear-weapon-generated electromagnetic fields with the aid of a high-speed digital computer. The technique is also applicable to problems of antennas in conductive environments subject to certain symmetry conditions. Stability and accuracy of the numerical technique are discussed, an internal consistency check is derived, and a test problem for the technique is developed. It is concluded that this numerical technique proved successful in calculating the electromagnetic fields generated by a nuclear weapon detonation. (Author)
