摘要：
A superconducting microwave ring resonator whose resonant frequency can be tuned is designed and simulated. The structure is a ring resonator directly coupled to two low inductance open loops with Josephson junctions fabricated in a thin film format. The frequency tuning is accomplished by changing the nonlinear equivalent inductance of the Josephson junctions. The designed resonator works with higher Q value than that from other tuning approaches and with a frequency tuning range of 18%. (C) 2003 Elsevier B.V. All rights reserved.
