TL;DR: In this article, the authors describe a very fast and flexible algorithm for the wideband modeling of arbitrarily shaped H-plane waveguide components, based on the evaluation of the poles and the residues of the Y-parameters by the "boundary integral-resonant mode expansion method."
Abstract: The paper describes a very fast and flexible algorithm for the wideband modeling of arbitrarily shaped H-plane waveguide components. The algorithm is based on the evaluation of the poles and the residues of the Y-parameters by the "boundary integral-resonant mode expansion method." It also permits the fast evaluation of the effect of a deformation on the frequency response, a feature very useful either for optimization or for setting the mechanical tolerances. Some examples demonstrate the efficiency, flexibility, and reliability of the method. They show that the frequency response of complicated structures, such as multicavity filters, can be calculated in times of the order of one minute (or less) on ordinary workstations.

TL;DR: In this paper, a fast tolerance analysis based on the BI-RME method is proposed to evidence the parts of the junction with higher sensitivity and to give the maximum permitted tolerances in the junction construction.
Abstract: The full-wave analysis of arbitrarily shaped waveguide junctions allows to realize compact and low-loss new structures The practical realization of these waveguide elements, however, suffers from technological and mechanical constraints, whose effect is to change in a random way their frequency behaviour We propose a fast tolerance analysis, based on the BI-RME method, able to evidence the parts of the junction with higher sensitivity and to give the maximum permitted tolerances in the junction construction This tool can help the designers in the choice of the best suited manufacturing technology and therefore in the analysis of the production costs
