In case of the MMCL operating in normal mode, synthesis is an iterative process of finding of MMCL topological sizes and the constructive parameters, which guarantee excitation and propagation of the single normal wave in the line at the applying specified modal voltage.
A survey of literature reveals that there is no well-established systematic design technique for synthesis of an MMCL, operating in the normal mode.
In this paper we propose an original synthesis technique of six-conductor symmetrically coupled MMCL, operating in normal mode.
The proposed synthesis algorithm of a symmetrically coupled MMCL is based on an iteration of calculation of modal voltages, and changing structure of the MMCL in order to find such structure of an MMCL, for which amplitudes of modal voltages are equal for every microstrip conductor.
The parallel algorithm for the analysis of the MMCL is proposed in this article.
Verification of the parallel algorithm, investigation of its effectiveness, and calculation results of five-conductor MMCL, operating in normal mode regime, are presented in Sections III.
So, to evaluate mentioned characteristics of the MMCL for c- and [pi]-normal waves, these four operations should be done: 1) to calculate capacitance per unit length of the conductors of the MMCL for c-mode; 2) to calculate capacitance per unit length of the conductors of the MMCL for [pi]-mode; 3) to calculate capacitance per unit length of the conductors of the MMCL for c-mode changing the dielectric substrate by air; 4) to calculate capacitance per unit length of the conductors of the MMCL for [pi]-mode changing the dielectric substrate by air.
In this case, every node will have initial parameters of the MMCL for which the conductors' capacitance per unit length will be calculated.
The distinctive feature of our MMCL is the finite number n of its conductors corresponding to number of the strips of the MMDL.
The basic characteristics of a MMCL are characteristic impedances ([Z.
Having calculated characteristics of the MMCL for each conductor, we (1) use the boundary conditions at the ends of the section of the MMCL, (2) calculate simple S scattering matrix for each MMCL strip, (3) apply topology of MMDL and calculate global S scattering matrix for investigated MMDL like in .
The calculated characteristic of the MMCL is presented by curve (a) in Fig.
