✦ Synopsis
neously magnetized ferrite planar disk is studied first. The obtained results are then used to compute the inhomogeneously magnetized planar ferrite circulator.
2. THEORY
From a practical point of view, it is assumed that the ferrite disk is magnetized along the axis of the disk z , and the dc magnetized field is dependent on the radial direction r and the azimuthal direction C#I only. The height of the disk is small, and the microwave electromagnetic fields are independent on the coordinate z . Two different methods are used in the study. They are as follows.
