Family of 12-, 6- and 3-parametrical algorithms for electrodynamic analysis of 3D stream R/spl tau/-net

Efficient computing algorithms based on division of an electromagnetic process in the stream R/spl tau/ grids in two independent processes are analyzed. It is shown that on the basis of the 12-parametric algorithm one can generate 2 variants of the 6-parametric algorithms: with usage of a half of the nodes or a half of the ports. A new more efficient 3-parametrical algorithm is found on the basis of combination of ideas of the mentioned algorithms, where a half of the ports and a half of the nodes are used.
