Abstract(in English)
We report the experimental result on microwave properties of superconductor-constrictions-superconductor (S-c-S) devices. In the absence of microwave irradiation the differential resistance dV/dI curve was good agreement with the theoretical curve calculated from single-Andreev reflection model. New microwave-induced steps up to 2.5mV were observed that differ from the features of the well-known "Shapiro steps". The amplitudes and spacing of the dV/dI peaks increased with bias voltage. The spacing did not correspond to the Josephson conditions 2eV=mhv, and not depended on microwave power P_
