【Abstract】 One of the most important problems in the use of Josephson junction arrays as mm/sub-mm microwave sources is the phase locking of the junctions. Using the resistively and capacitively shunted Josephson junction model,we study the phase locking properties of junction arrays shunted by a common resistor. The results include the influence of the parameter spread of the critical current,the McCumber parameter and the number of the junctions on the phase locking properties.更多还原
