Abstract

In this paper, the genetic algorithm (GA) is employed as an efficient optimization tool to derive SPICE-type equivalent circuits of microwave components, and of discontinuities in coaxial lines, from their specified S-parameters. Nodal analysis and techniques are utilized in conjunction with the GA to extract these equivalent circuits, whose component values are the parameters optimized by the GA. Numerical examples, that demonstrate the fact that GA yields excellent results for the cases studied, are included in the paper
