Coupling of a method of moments adapted to planar circuit and volumic methods

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. The considered problem is the Helmholtz equation in the frequency domain. Two test cases are provided to validate the proposed hybridization principle.
