Abstract :
Josephson oscillators attract a considerable interest as parts of superconducting electronic devices. Numerical simulation of Josephson oscillator in resonator was performed at arbitrary coupling. Parametric excitation is indicated by voltage break at dc IV-curve of Josephson oscillator. A numerical procedure was developed for calculation of static characteristics of the oscillator at any coupling with resonator. The influence of thermal fluctuations of normal electron current on parametric excitation was analyzed. The results obtained can be used in development of electronic devices, based on Josephson oscillators in mm- and sub-mm wavelength spectral range of electromagnetic radiation.
