Abstract :
A combination of the boundary element method in the junction, using a Green´s function approach and multimode expansions in the outgoing planar transmission lines, has been proposed. The multimode S-parameters are calculated with good accuracy from a simple identification in the system of equations given by the boundary element method. In addition to a considerable gain of computing time with this method, it is easy to handle inhomogeneities and complicated structures.
