L'hybridation entre la WCIP (Wave Concept Iterative Procedure) et des méthodes volumiques comme la FDTLM (Frequency Domain Transmission Line Method), la FEM (Finite Element Method) et la méthode HDG (Hybridizable Discontinuous Galerkin) est présentée dans cet article. Le problème traité est celui de l'équation des ondes dans le domaine...

To study and design complex microwave circuits, we aim at hybridizing the method of moments called the Wave Concept Iterative Procedure with the Hybridizable Discontinuous Galerkin method. The goal is to take advantage of the low number of unknowns provided by the MoM with a surface mesh and to deal with inhomogeneous substrates with the...

Hybridization between the WCIP (Wave Concept Iterative Procedure) and volumic methods like the FDTLM (Frequency Domain Transmission Line Method), the FEM (Finite Element Method) and the HDG (Hybridizable Discontinuous Galerkin) method is presented in 2d in this paper.
