Description

technical field [0001] The invention belongs to the technical field of superconducting electronics, and in particular relates to the design of a high-temperature superconducting film microwave surface resistance distribution testing device and method. Background technique [0002] The microwave surface resistance of high-temperature superconducting films in the liquid nitrogen temperature zone is 2-3 orders of magnitude lower than that of conventional good conductors. This low-loss characteristic makes high-temperature superconducting microwave passive devices based on high-temperature superconducting films have Excellent characteristics that cannot be compared with conventional devices. According to the structural characteristics of the high-temperature superconducting film itself, its microwave surface resistance is not uniform. As the circuit of superconducting devices becomes more and more complex, the consistency of superconducting film materials becomes increasingly pr...
