Description
Summary:In this paper we adapt a novel mode-matching and method of moments hybrid technique to efficiently analyze substrate integrated waveguide based devices. The hybrid technique is formulated in terms of a single equivalent current. This fact is used to include the emergent modal weights, i.e. the scattering parameters, as unknowns of the method of moments system of equations. In this case, it is relatively easy to develop fast frequency sweep schemes that can be used to highly accelerate the solution of an arbitrary device and, as a result, a very efficient technique is obtained. This technique can be applied to the analysis and design of substrate integrated waveguide devices, and it is highly competitive when compared to other method of oments and mode-matching hybrid formulations or when compared to reference ommercial software.
