Boundary element method with high order impedance boundary condition in electromagnetism
Résumé
The present paper introduces a surface formulation to solve the scattering problem for coated objects using the integral method and a high order impedance boundary condition (HOIBC). We study the existence and uniqueness of the solution, and we propose a discretization of this formulation trough Rao-Wilton-Glisson functions (RWG). Numerical results are obtained with a 3D MoM code running on MPI clusters. The experiments show how the HOIBC significantly improves the accuracy of the results compared to computations using the standard impedance boundary condition (SIBC).
