Contemporary computational electromagnetics tries to deal with the problems complexity utilizing several different approaches. One of the oldest relies on exploiting symmetries, which allows describing the problem at hand, using reduced number of unknowns. This approach is often applied to problems characterized with rotational symmetry of the geometry, leading to a class of so-called body-of-revolution (BOR) algorithms [1],[2]. Another approach, which becomes popular recently, is subdividing of the original problem into several partial sub-problems, which can be solved separately, and then combined into the final complex solution. This is called the domain-decomposition method (DDM) or the diakoptics method [3],[4]. In this paper we combine the two aforementioned techniques for problems involving multiple composite metal-dielectric objects, which possess one symmetry axis. The method is validated by comparison with literature data concerning scattering by two spheres.
