Application of the CBF Method to the Scattering by Combinations of Bodies of Revolution and Arbitrarily Shaped Structures

Abstract

In this paper, an algorithm is described which enables efficient analysis of electromagnetic scattering by configurations consisting of arbitrarily shaped conducting bodies and conducting bodies of revolution (BoR). The well-known problem resulting from the loss of azimuthal mode decoupling, when in addition to BoR geometry there exists a body that does not belong to the rotational symmetry of the BoR, is circumvented by the use of characteristic basis function (CBF) method. This however requires careful implementation of the method in order to obtain stable and efficient procedure.
