Frequency analysis of the voltage oscillation of an achyphen; and dchyphen;currenthyphen;biased resistively shunted Josephsonhyphen;junction analogue

摘要

We have frequency analyzed the voltage osicllation of a currenthyphen;biased resistively lshunted Josephsonhyphen;junction (RSJ) model. In particular we have been interested in the situation where there is an ac (microwave) hyphen;induced step in theIhyphen;Vcharacteristic. Conversion of the Josephson oscillation into other frequency modes is studied under various bias conditions.
