High Order Impedance Boundary Condition for the Three-dimensional Scattering Problem in Electromagnetism

Soumaya Oueslati, Christian Daveau, Abil Aubakirov

In this paper, we propose a variational formulation with the use of high order impedance boundary condition (HOIBC) to solve the scattering problem. We study the existence and uniqueness of the solution. Then, a discretization of this formulation is done with Rao-Wilton-Glisson (RWG). We give validations of the HOIBC obtained with a 3D MoM code that show the improvement in accuracy over the standard impedance boundary condition (SIBC) computations.
