Аннотация: Josephson and quasiparticle currents in SNcNS contacts are calculated for the regimes of ballistic constriction ''c''. The relation between the current and electronic densities of states in NS proximity bilayer is found. The effect of the proximity N laver on the Andreev and normal reflections of electrons at the constriction is studied. Excess current at large voltages and subharmonic structure at low bias are analyzed as a function of material parameters of N and S and transparency of the NS interface. The appearance of new series of subharmonic peaks due to two-gap structure in the density of states of proximity NS electrodes is demonstrated. The relation between excess and critical currents is analyzed. The model is relevant for SNS junctions of constricted geometry which is realized in S-2DEG-S and step-edge high T-c SNS contacts.
