Transmission Through Arbitrary Apertures in Metal-Coated Dielectric Bodies

We present a new variational direct boundary integral equation approach for solving the scattering and transmission problem for dielectric objects partially coated with a PEC layer. The main idea is to use the electromagnetic Calder'on projector along with transmission conditions for the electromagnetic fields. This leads to a symmetric variational formulation which lends itself to Galerkin discretization by means of divergence conforming discrete

Direct computation of static difference magnetic field in nonlinear magnetic materials and application to shape reconstruction of damaged areas in aging materials

In order to accurately compute the magnetic field variation due to changes in material properties (e.g. material aging) we propose a technique that computes directly the difference magnetic field. Nonlinear materials are analyzed by means of the polarization technique. The linear field problem is solved using a fast Green function approach. A 2D formulation is validated upon comparison with measurement data. Then it is used as fast forward solver
