The influence of the critical current spread on the frequency locking of Josephson junctions in two-dimensional arrays

A study was conducted to examine the two-dimensional arrays of overdamped Josephson junctions under microwave irradiation. Arrays of 10 Josephson junctions were utilized in the study while the electron beam was determined at a frequency of 20 kHz. Results indicated that the critical current spread influences the arrays' behavior under microwave irradiation. They also indicated a close association between the dynamic resistance and frequency locked junctions.
