A New Method for Fitting of Frequency Domain Responses by Rational approximation in Electromagnetic Transients Studies

The paper describes a general methodology for fitting of measured or calculated frequency domain responses with rational function approximations. This is achieved by replacing a set of starting poles with an improved set of poles calculated by a new method. This new method can fit functions with a high number of resonance peaks Property. The method is demonstrated to be very suitable for fitting network equivalents, transformer responses and transmission line with large asymmetry.
