摘要:
The rf impedance of a superconducting weak link with negligible capacitance is calculated for a variety of operating conditions. It is shown that the impedance is always real between harmonic steps of theI‐Vcharacteristic. The real part of the impedance is negative under certain conditions of bias for small rf signals, thus indicating the region of self‐oscillation of the weak link.
