Abstract

The electromagnetic scattering from composite anisotropic dielectric and conducting structures is modeled by hybrid partial differential equation-integral equation formulations. We emphasize the role of edge elements for both the partial differential equation and the integral equation discretization and for the coupling of the two. Numerical results from the various formulations are presented and measurements are compared in order to obtain test cases for the development and validation of numerical methods
