Optimized analysis of slotted substrate integrated waveguides by a method-of-moments mode-matching hybrid approach

A full-wave hybrid formulation is proposed for the efficient and accurate modeling of substrate integrated waveguides by rigorously accounting for all possible interactions among elements such as vertical metallic or dielectric posts and coupling or radiating slots. The method is specifically accelerated in order to maximize the efficiency of the analysis of common structures. Its flexibility allows for the study of a large class of devices, possibly in stacked-waveguide configurations, and for the characterization of radiated fields and input port parameters.
