Abstract
This paper reviews two hybrid (frequency domain) finite element methods for electromagnetic scattering applications. Specifically, the progress over the last five years or so is reviewed as it pertains to the finite element method when combined with the boundary integral or the absorbing boundary conditions for truncating the computational domain. After a brief presentation of the associated mathematical formulations, we review two and three dimensional applications of the aforementioned methods. In addition, a brief review section on the popular element shape functions is included.

Le progrès sur les cinq dernières années fait par la méthode ďéléments finis pour la troncature du domaine de calcul grâce aux intégrales de frontière ou aux conditions absorbantes de frontière est analysé. Après une brève présentation des formulations mathématiques, des applications à deux et trois dimensions des méthodes présentées sont étudiées.
