Abstract(in English) We made a numerical simulation based on the resistively shunted junction model to reveal the phase locking stability associated with the enhanced ac Josephson effect. By using a pulse train-like signal, the ac Josephson effect is remarkably enhanced. This is due to the individual phase locking between rf-signal and Josephson oscillation which is interpreted in the viewpoint of the pendulum-like motion in which is a measure of the phase locking stability, where φ denotes the phase difference for both sides of the junction. The pulse train-like signal results in the enhanced stability of the phase lock in positive- or negative- current region of the current-voltage curve. The results obtained here can be used for the design of voltage standards.
