PARALLEL SYNTHESIS OF MULTICONDUCTOR MICROSTRIP LINES / LYGIAGREČIOJI DAUGIALAIDŽIŲ MIKROJUOSTELINIŲ LINIJŲ SINTEZĖ

The parallel technique for the synthesis of the multiconductor microstrip lines (MML) is presented in this article. Main parameter of the synthesised MML is characteristic impedance, variable parameters: width of the conductors, space between conductors, the thick of dielectric substrate and its permittivity. Authors’ created parallel algorithm is used in this technique, wherein analysis operations are distributed among cluster nodes. The MML model created using the finite difference method. To reduce analysis area it is assumed, what MML is infinite and periodic. Proposed technique was realized and proved in the sixteen nodes cluster. Cluster is based on Mpich2 software. Proved, that synthesis error is less than 1 %. Characteristics of the synthesised MML, compared with characteristics which calculated with other methods differ less than 6 %. It may be noted that, performance coefficient of the parallel synthesis algorithm is growing linear when cluster has no more than 16 nodes. Linear growth of performance coefficient demonstrates that adding more nodes to cluster reduce execution time of the synthesis.
