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(More)
Approximate, non-singular kernels are often used in moment-method formulations coping with thin-wire structures. Their use has important consequences, one of which is the appearance of oscillations in the computed currents when the number of sub-domain basis functions is sufficiently large. These oscillations are not due to round-off errors. In this paper,(More)
Electromagnetic Scattering from Discrete Bodies of Revolution (DBOR's) is performed by invoking a recently developed, recursive linear system direct solver. The problem is initially formulated via a standard Moment Method (MoM) with point matching, however the DBOR symmetry is taken into account to simplify calculations. Specifically, the MoM matrix is cast(More)
