Network folding strategies for concurrent electromagnetic field mapping

A number of concurrent algorithms for dynamic field mapping based on the two-dimensional lumped circuit analogies of Maxwell´s equations are presented. Specifically, some folding (ORIGAMI) and unfolding (SPAWNING) strategies for concurrent solutions of electromagnetic field electrical equivalent networks are presented. The methods illustrated are efficient in the mapping of large lumped equivalent circuits onto transputer arrays. The resulting algorithms implemented in ORIGAMI and SPAWNING versions are computationally efficient when compared with their sequential counterparts. The concurrent diakoptics methodologies based on Kron´s equivalent network approach would appear to offer advantages for dynamic field modeling when compared with more traditional numerical approaches.<>
