Most commercial electromagnetic (EM) simulators designed for MIC and MMIC work are based on integral equations and the method of moments (MoM). EMPOWER is based on the method of lines (MoL). This technique has excellent error convergence properties and submits well to code optimization to minimize numeric complexity.
The root of EMPOWER is work which began in 1987 at the Novosibirsk Electrical Engineering Institute. This lead to the commercial development of TAMIC in 1991 in Moscow. TAMIC saw commercial use in the Soviet Union and elsewhere. In late 1996, Eagleware acquired TAMIC and the principle contributor joined Eagleware to begin significant improvements. The code was integrated into the GENESYS environment at release Version 6.5 in 1998.
