Abstract(in English) | Numerically-simulated properties of an RF-field-driven SQUID (superconducting quantum interference device) model are presented. In the model, an RF signal is coupled with the SQUID loop magnetically. By comparison with the results of the conventional RF-current-driven junction model in literature, simulated RF responses of the RF-field-driven SQUID model exhibit enhanced nonlinearity (e.g., larger Shapiro steps) for a wider frequency range. Two anomalous experimental results of YBa_2Cu_3O_<7-δ> grain boundary Josephson junctions are numerically reproduced by using the RF-field-driven SQUID model. The one is the magnetically-enhanced Shapiro steps under THz signal irradiation, and the other is the step-like-structure under GHz signal irradiation. |
