Foster impedance data modeling via singly terminated LC ladder networks

In this work, a lossless model is developed for the given Foster impedance data. In the model, a 2-port short- or open-terminated LC ladder is used. After applying the proposed algorithm, a realizable driving-point reactance function that fits the given data is obtained. Next, this function is synthesized, resulting in the desired model. In the algorithm, there is no need to select a circuit topology for the model. Two examples are given to illustrate the utilization of the proposed modeling algorithm.
