Surface Current and Charge Density Induced on an Infinite, Perfectly Conducting Circular Cylinder in the Presence of Finite Axial Thin Wire - Transverse Magnetic Case

摘要

The induced surface current and charge densities are evaluated on an infinitely long circular cylinder in the presence of a set of axial wires. The incident field is taken as a TM sub z polarized plane wave in the principal plane. The method used for the calculations is a hybrid solution which combines the eigenfunction solution for a circular cylinder (infinitely long) and the reaction integral equation formulation for thin axial wires. In principle, this solution is a modified moment method technique which employs cylindrical Green's functions in order to introduce the effect of the infinitely long circular cylinder into the problem. The fields penetrated by the axial dipoles are also given in terms of the cylindrical Green's functions.
