Abstract

Broadband classical detection of THz radiation by a YBaCuO Josephson junction was studied on the basis of resistively-capacitively shunted junction model. Numerical simulation was based on the parameters of the samples experimentally studied in other works at nitrogen temperatures. It is shown that taking into account the damping of the Josephson junction becomes essential for high frequencies of external signal. The absolute value of responsivity decreases as junction capacitance increases. Damping parameter also influences the choice of optimal IC and RN parameters.
