“…Applying solution of (16) to coupled-mode method (CMM) a gyromagnetic coupling coefficients, propagation coefficients of ferrite modes and scattering matrix of CFCL junction can be determined [3,11,27]. In this approach the transversal electric and magnetic fields in the investigated ferrite guide are expressed in terms of basic guide field eigenfunctions e t,e(o) and h t,e(o) as follows: …”

“…Nonreciprocal devices have been extensively used in modern microwave and millimeter systems [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. In order to obtain the nonreciprocal effects one needs to utilize the ferrite materials [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] or active elements such as amplifiers [16].…”

Abstract-In this paper, a novel longitudinally magnetized cylindrical ferrite coupled line (CFCL) junction is proposed. In comparison to planar ferrite coupled line (FCL) configurations, which are well known in literature, in such structure the higher gyromagnetic coupling occurs. This allows to obtain the required in FCL devices 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 CFCL junction a hybrid technique combining method of moments and coupled mode method (MoM/CMM) is applied. The results are compared with the ones obtained from commercial software HFSS and a good agreement is obtained.

Abstract-This paper presents the investigations of nonreciprocal devices employing a novel ferrite coupled line junction. The structure is designed using coplanar line technology with the ground half-planes reduced to the strips. The investigated junction is composed of one ferrite section placed in between of two dielectric sections. In the ferrite section the longitudinally magnetized ferrite slab is located at the top or the bottom of the strips and is covered with the dielectric layers. In the dielectric sections the ports of the junctions are located. The wave parameters and field distributions of the modes propagated in the dielectric and ferrite sections are obtained from spectral domain approach. In order to determine the scattering matrix of the junction the mode matching method is utilized. The investigation of the circulator and isolator designed based on the Smatrix of the junction are presented. The obtained results are verified by comparing them with HFSS simulations and own measurements of the fabricated devices. In both cases a very good agreement is observed.
