Fast Field Computation of Ferrite Junction Circulators by Finite Difference Method with Comparison by Bosma’s Green’s Function

The main subject of this paper is the analysis of stripline ferrite junction circulator using the finite difference method with complete formulation. Finite difference method is very fast and simple in comparison with other methods such as finite element used by HFSS. Although finite difference method is applied on ferrite junction circulator, this convenient method also can be used for any ferrite planar circuit in microwave integrated circuits. The Analysis of Yjunction stripline circulator using Green’s function method was also reported in the literature. The results of finite difference method and Green’s function method are compared
