Volume Integral Equation using Solenoidal Basis Functions

This paper studies the application of the basis functions proposed by Carvalho and Mendes (1999), which are defined on tetrahedrons, in the analysis of the electromagnetic scattering problem of the three-dimensional homogeneous or inhomogeneous dielectric objects. Necessary formulations for implementation, especially the process of singular integral emerged in the method of moments are given by a mathematical trick. Numerical results suggest that the proposed approach is a effective one.
