Abstract :
We introduce a new technique for the efficient CAD of a class of waveguide components. The basic idea is to apply the Finite Element Method/Mode-Matching (FEM/MM) technique in a direction different from the propagation one, by using a Modified Transverse Resonance (MTR) approach. In this way it is unnecessary to use a fully three-dimensional numerical electromagnetic simulator and several frequency points are computed by just one analysis.
