Abstract
Waveguide bends of complex geometrical shape frequently occur in micro wave systems. To make an accurate prediction of the bend's electrical performances it is useful to employ a general numerical algorithm, suc h as the finite element method (FEM), which is able to cope with compl ex geometries. However, since in common practice bends are manufacture d either on the E- or H-plane, the FEM can be significantly simplified for these cases, thus enhancing its numerical efficiency. In this art icle, it is illustrated how the FEM can be simplified and it is shown, by means of several examples, how it can be applied to the case of a straight waveguide which is bent and clamped to obtain low return loss es.
