Y. Mizugaki et al., Numerical evaluation for the high-frequency response of Josephson junctions having finite capacitance, JPN J A P 1, 37(11), 1998, pp. 5971-5972
The high-frequency response of a Josephson junction is numerically investig
ated. The resistively shunted junction (RSJ) model and the resistively and
capacitively shunted junction (RCSJ) model are employed. Simulation results
for the Shapiro steps are different between the two models. The difference
with respect to the RF current is explained by employing a simple resistor
and capacitor model.
