| Abstract: | In this paper an exact analysis of 3-D field theory treatment for H-plane waveguide Y-junction circulators with partial ferrite post is presented by using the mode matching method. The field analysis yields characteristic equations, which determine propagation constants in the partial ferrite structure. The properties of the field distribution in the ferrite region is derived, and some vague or error concepts of the electromagnetic field in the ferrite region are cleared. Through numerical calculation, the effects of the structure dimensions and material parameters on the circulator characteristics are obtained. The calculated results of X-band circulators agree with experimental results. |
