✦ Synopsis

Half-harmonic generation in Josephson tunnel functions and microbridges is investigated theoretically, numerically, and experimentally. It is found that such generation may take place both at zero voltage and on rf-induced steps in tunnel/unctions, but not in microbridges. A simplified theory, which leads to the definition of a plasma resonance on rf-induced steps, is presented. The experiments are made on/unctions with different current densities and with pump frequencies at 18 and 70 GHz.
