Efficient Analysis tool of Inductive Passive Waveguide Components and Circuits using a Novel Spatial Domain Integral Equation Formulation

This paper presents an efficient software tool for the analysis of inductive waveguide components using a new spatial domain integral equation formulation. For the first time the Kummer and Ewald series acceleration techniques are combined into a single formulation for the efficient evaluation of the spatial domain parallel plate waveguide (PPW) Green's functions. Results are presented for complex microwave filters containing dielectric posts and rounded corners, showing the accuracy and usefulness of the proposed approach.
