Description
Summary:In this paper a longitudinally magnetized cylindrical ferrite coupled slotline (CFCSL) junction is presented. In comparison to planar ferrite coupled line (FCL) configurations, which are well known in literature, in such structure the effect of the gyromagnetic coupling is much higher. This allows one to obtain the Faraday rotation angle π/4 for the ferrite with shorter length and lower value of magnetization. As a result the total insertion losses in the ferrite section can be reduced using the proposed topology. In the analysis of the proposed CFCSL junction a hybrid technique combining method of moments and coupled mode method (MoM/CMM) is applied.
