TI - Method of Fundamental Solutions for Scattering Problems of Electromagnetic Waves T2 - Computer Modeling in Engineering \& Sciences PY - 2005 VL - 7 IS - 2 SN - 1526-1506 AB - The applications of the method of fundamental solutions (MFS) for modeling the scattering of time-harmonic electromagnetic fields, which are governed by vector Helmholtz equations with coupled boundary conditions, are described. Various perfectly electric conductors are considered as the scatterers to investigate the accuracy of the numerical performance of the proposed procedure by comparing with the available analytical solutions. It is also the intention of this study to reveal the characteristics of the algorithms by comparisons with other numerical methods. The model is first validated to the exact solutions of the electromagnetic wave propagation problems for the scatterers of a circular cylinder and a sphere. The radar cross sections (RCS) of a prolate spheroid are then presented to illustrate the predictive capability of the algorithms for more complex geometric shapes of the scatterers. The present investigation has demonstrated that the MFS technique is simple, efficient, and accurate for modeling 2D and 3D electromagnetic scattering problems.
