Scattering of EM waves by homogeneous dielectrics with the use of the method of moments and 3D solenoidal basis functions

The use of rectangular and triangular basis functions with the method of moments to analyze the problem of scattering of electromagnetic waves by dielectric objects with high dielectric constant (ϵ r> 10) leads to convergence problems due to the spurious charges associated with the basis functions. In this article we use the method of moments and a solenoidal 3D basis function to analyze the scattering of EM waves by homogeneous dielectric objects. We present results showing the effectiveness of the formulation.
