Abstract
We report calculations of current‒voltage characteristics (I‒V characteristics) of Josephson junctions using the resistive model. The I‒V characteristics are found to be stable to deviations of the dependence of the superconducting current on the phase difference (φ) of the order parameter at the junction boundaries from the simple sinusoidal one, characteristic of ideal Josephson junctions. It is shown that to analyze the processes occurring in Josephson junctions, it is important to measure the spectral composition of generation from these junctions.
