Abstract
An efficient iterative finite element method for solving a three-dimensional scattering problem is proposed. With only a small number of meshes around a three-dimensional scatterer, the typical finite element method is shown to give an exact solution by carrying out several iterative updates of the radiation-type boundary conditions. The proposed method is used to analyse the scattering from a three-dimensional cavity-backed aperture, and the results obtained show good agreement with data obtained using another method
