Extension of image theory for analysis of a wire parallel to a circular cylinder
Abstract
A simple and efficient approach to compute the input impedance and current distribution on a wire parallel to an infinitely long, perfectly conducting circular cylinder is presented. It consists of solving for the wire above an infinite ground plane using standard thin-wire moment method (MM) procedures, but appropriately modifying the field due to the image segments by a geometrical constant. Comparison with measurements shows the validity of the technique, which can be easily implemented in any MM code.
