Abstract :
New expressions for the numerical evaluation of the ´full´ or ´exact´ thin wire kernel for wire antennas are presented. They allow for fast and accurate method of moments calculations of wire models with arbitrary segment length/radius ratios. The new expressions are shown to converge with respect to mesh refinement and to be applicable to highly complicated structures.
