This paper presents a quantitative comparison between the vector ï¬nite element method with local absorbing boundary condition (a classic differential technique) and the divergence-conforming boundary element method (an edge-based element integral method) applied in solving three-dimensional electromagnetic scattering problems. The results point out the applicability of each method. For finite element method, three different techniques to calculate far fields are analyzed.
