Abstract :
The paper introduces an approach for rational macromodeling based on magnitude frequency data. This is achieved by fitting the magnitude square function using vector fitting (VF) with symmetrical basis functions. The procedure is demonstrated to be more robust than a direct application of VF to the magnitude square function.
