Open-region, electromagnetic finite-element scattering calculations in anisotropic media on parallel computers

Open-region scattering calculations for complex, electrically large scatterers remains a difficult modeling and simulation problem. The finite-element method (FEM) has been shown to be a viable approach to solving such problems. However, conventional methods on serial computers limit the size which can be tackled with the FEM. In this paper, we demonstrate the use of both a PML boundary condition along with a parallel solver for tackling large, complex problems containing scatterers which are inhomogeneous and anisotropic.
