Far-field results obtained by two different methods for the problem of electromagnetic scattering from dielectric objects are compared. The two methods are the surface integral formulation utilizing equivalent electric and magnetic surface currents and the volume formulation utilizing the equivalent electric polarization current. Triangular patches are used in the surface formulation and cubical cells are used in the volume formulation. The far-scattered fields, obtained by both the methods, are in good agreement thereby validating both the approaches for the analysis of scattering problems. The numerical problems associated with the evaluation of the fields in the source region have also been addressed.
