Abstract
A finite-element method (FEM)-based hybrid method (or iterative FEM) is suc cessfully applied to a three-dimensional (3-D) scattering problem without t he effect of internal resonance. With only a small number of meshes around a 3-D scatterer, this FEM is shown to give an accurate result through sever al iterative updates of the boundary conditions. To confirm the efficiency of this method, scattering from a 3-D cavity-backed aperture is analyzed an d the results obtained are compared with the same obtained by another conve ntional method.
