摘要：

In this paper, the MPSTD algorithm is applied to model longitudinal slot in the broad face of rectangular waveguide. Firstly, an approach of dividing the total-field and the scattered-fleld is proposed based on the characteristic variables of Maxwell's equations. And the updating equations of the field on the interface between the scattered-field domain and the total-field domain have been derived. Secondly, the setting of excitation source is proposed by the idea of domain partition, which makes the domains of incident-field, scattered-field and total-field contacted avail-ably. So it is convenient to introduce the incident-field and calculate the scattered-field. The resonant length and impedance characteristics of longitudinal slot are analyzed by MPSTD. The numerical results indicate that the MPSTD algorithm is accurate and efficient to analyze the longitudinal slot in the broad face of rectangular waveguide.
