EMP Generation Near Objects with Cylindrical Symmetry in the Source Region.
Abstract
Large electromagnetic fields and currents can be induced on an object immersed in the EMP source region of a near-surface nuclear explosion. If the object is a body of revolution with length much larger than the skin depth of the EMP environment, it can be treated as if it were cylindrical. Solved is such a circular cylindrical source region problem with the incident photons parallel to the cylindrical axis, having negligible attenuation, and encountering no environmental changes along the axis in the region of interest, by analysis and by a numerical code RONDINE which is obtained by slightly modifying the planar code ONDINE. The RONDINE is applicable to any circular cylindrical, stratified source region problem. In particular, the results for a conducting wire in the source region are obtained from RONDINE and are calculated from analysis. They are compared and exhibit very good agreement. In addition, the effect of magnetic field turning on Compton electrons is investigated and found to substantially reduce the current on the wire.
