At present, magnetized ferrites have been applied to such nonreciprocal microwave or millimeter wave devices as isolators, circulators, and phase shifters. So a significant amount of research and many analyses have been carried out to develope such devices. To obtain more exact evaluations of the properties of these devices with their complicated structures and the medium conditions, involving the tensor permiability of the ferrite, it is necessary to be analyzed in three-dimensional space. Also, by the recent development of the high-speed digital technology, it becomes important to analyze the electromagnetic fields on time domain. However, most of the conventional studies for these devices have been performed by the steady state and two-dimensional analyses. The authors have been proposed a new-method, that is, the spatial network method, for the transient analysis in three-dimensional space. The method is based on the equivalent circuit of Maxwell's equation and the formulation by Bergeron's method. By applicating the method to the magnetized ferrite, this paper presents the electromagnetic properties of the twin ferrite plates type phase shifter of the rectangular waveguide.
