Comparison of MoM/SIE, MoM/VIE and FEM based on topological analysis of two canonical problems

Analysis of composite metallic and dielectrics structures placed in a time-harmonic electromagnetic field is usually based on the MoM (Method of Moments), or FEM (Finite Element Method). Particularly, if MoM is applied to SIE (Surface Integral Equation), the method is termed as MoM/SIE, and if MoM is applied to VIE (Volume Integral Equation), the method is termed as MoM/VIE. Besides that, all these methods can be mutually combined giving different types of hybrid methods. The authors present a comparison of the MoM/SIE, MoM/VIE and FEM methods based on a topological analysis of two canonical problems.
