Abstract
We perform a Method-of-Moments (MoM) analysis of a circular array of cylindrical dipoles. Such arrays are known from earlier theoretical and experimental studies to possess very narrow resonances. The earlier studies were carried out using the “two-term theory.” The present work is a direct continuation of a recent paper showing that the problem possesses unique and particular difficulties. The main difficulties are overcome herein using a set of improved kernels in the usual Halliin-type integral equations (these kernels had been developed in previous works, and were successfully incorporated into the aforementioned two-term theory analyses). We make a comparison of our MoM results to two-term theory results for the case of a 20-element array.
