Hybrid numerical electromagnetic modeling techniques for analyzing printed circuit board geometries

Keywords and Phrases

Hybrid FEM/MoM; Hybrid FEM/SPICE; Absorbing boundary condition


"This dissertation discusses three topics relevant to the improvement of hybrid numerical electromagnetic techniques. These techniques can be applied to a variety of problems, but the primary focus of this work is modeling printed circuit boards. The first topic describes an approach to transform the FEM matrix equation into equivalent circuits and applies this approach to the modeling of power bus structures. The equivalent circuits can then be analyzed using SPICE programs. The remaining topics discussed in this dissertation relate to hybrid FEM/MoM methods that combine the finite element method (FEM) and the method of moments (MoM) to model inhomogeneous unbound problems. The second topic applies a fast multipole method to reduce the computational complexity associated with the MoM part of the hybrid method. The last topic presents effective preconditioners for the solution of the hybrid FEM/MoM matrix equation using combined formulations. The effective preconditioners are derived from the FEM and absorbing boundary condition (ABC)"--Abstract, page iv.
