“…Any ferrite shape that has the three-fold symmetry could be used as the junction. The disk and the triangle are the two simplest shapes, which are the ones used in nearly all the commercial circulators [1,2]. The planar circulators with the ferrite ring have been designed and analyzed to operate at the single or the double circulation frequencies [3].…”

Abstract|Experimental Results of the Y-junction microstrip circulator with a ferrite sphere have been reported in the literature. In this paper, the nite di¬erence time domain (FDTD) method is used to analyze this kind of circulator. Comparisons between the experimental results and our numerical results con rm the validity of our program. The pro les of the power-density ®ow inside the ferrite sphere are given and the e¬ects of circulator parameters on circulation characteristics are investigated to further understand the performance of the circulator with a ferrite sphere.
