In this model, the high frequency capacitive PT/CT model and the multi-terminalnetwork model for grounding system are included using rational functions by means of vector fit-ting based on test data.
Every part of the compound ultrasonic torsional vibration horn is equivalent to a four -terminalnetwork in this paper. Simplify the networks by multi-plying the matrices.
