Abstract: A method for calculation of static characteristics of Josephson junction
coupled with external electromagnetic resonant system and a computer program
based on it are presented. Resistively shunted model is used for description of
Josephson junction. Resonant system is presented by an equivalent circuit,
which consists of an arbitrary number of RLC circuits. Thermal fluctuations of
normal electron currents are taken into account in calculations. Simulation of
the junction, which is strongly coupled with a resonator, was performed, and IV-curve
features related with parametric resonance were obtained at various
temperatures.
Key words: superconductivity, Josephson junction.
