Abstract :
In this paper a new and efficient method for characterizing microwave components in the time domain is presented. It is based on the transmission line matrix (TLM) discretization of a discontinuity terminated at close range by means of a modal Johns matrix (wideband absorbing boundary). The results for individual discontinuities are then cascaded to obtain the characteristics of the overall structure. The efficiency of the new approach is demonstrated with the study of an inductive iris-coupled filter in a waveguide involving a hybrid representation of the different subsections
