A mixed-FEM and BEM coupling for a three-dimensional eddy current problem
ESAIM: Modélisation mathématique et analyse numérique, Volume 37 (2003) no. 2, pp. 291-318.

We study in this paper the electromagnetic field generated in a conductor by an alternating current density. The resulting interface problem (see Bossavit (1993)) between the metal and the dielectric medium is treated by a mixed-FEM and BEM coupling method. We prove that our BEM-FEM formulation is well posed and that it leads to a convergent Galerkin method.
