The Bymoment Method for Two-Dimensional Electromagnetic Scattering

Research output: Contribution to journalArticlepeer-review


The bymoment method is presented for the analysis of two dimensional electromagnetic wave scattering in an unbounded region. The method introduces a conforming surface to geometrically decouple the interior region containing the scatterer from the exterior region extending to infinity. The solution in the interior is generated using the standard finite-element solution of an interior Dirichlet boundary-value problem. The interior solution is then coupled to the exterior by an elegant use of Green's theorem in the unbounded exterior region. The validity of the method and the associated computer program is demonstrated by comparing our results to those of other methods for scattering by various cylindrical geometries.
