© 2016 IEEE. This contribution presents a formulation based on the integral equation technique for the analysis of waveguide circuits containing capacitive obstacles, and including material bodies, such as dielectric or magnetic posts. The formulation is very efficient, since it reduces the 3D structure to a 2D problem by using a mixed spatial and spectral formulation. Results show high accuracy and efficiency in the analysis of lowpass filters in waveguide technology. Using the software tool, several new applications in the area of waveguide lowpass filters are introduced. This includes the use of magnetic materials to implement resonant irises, and the use of dielectric materials to reduce multipactor risk in high power applications.
