Electromagnetic response of a conducting cylinder of finite length

Abstract

The electromagnetic fields are calculated for a truncated cylinder excited by a loop source and, for comparision, for excitation by a line source. These results are also compared with the infinite cylinder case. It is found that the relative importance of the azimuthally symmetric component of the current is diminished when the cylinder is truncated. This paper is prompted by the cogent suggestions of S. K. Singh concerning the possible importance of the symmetrical current induced in elongated ore bodies by certain electromagnetic source configurations used in geophysical exploration.
