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 Discontinuous Galerkin method. Indeed, the Wave Concept Iterative Procedure fails to address these structures. To limit memory storage, Domain Decomposition is considered for the Discontinuous Galerkin method to allow bigger linear systems.
