Analysis of NURBS dielectric volumes by using the Method of Moments

The analysis of dielectric volumes by using the Moment Method is presented in this paper. The discretization with tetrahedrons or hexahedra are the most common techniques for analyzing dielectric volumes with this technique. The simplest methods for the mesh generation and the analysis work with flat elements (every faces of the tetrahedrons or hexahedra are planar), but meshes of high resolution are required to obtain accurate results. In this work, a mesh generator that generates body-fitted hexahedra is presented together an implementation of the Method of Moments that works with NURBS volumes for analyzing this kind of meshes efficiently. The combination of the two techniques allows studying dielectric volumes by using less dense meshes than the required with the planar ones. To validate both methods, different benchmark cases are summed up in the results section.
