Abstract :
In this paper, a direct mode-matching technique is proposed for the calculation of the modal scattering matrix of nonconfocal, twisted, and/or displaced step discontinuities in elliptical waveguides of different cross sections, For the convenient treatment of the Mathieu functions, an efficient trigonometric series expansion technique is used, As examples, the scattering parameters are calculated for typical step discontinuities demonstrating the flexibility of the method
