Abstract
The conductance of a normal metal film (N) in contact with two superconductors (S) is calculated in the presence of a constant\(\bar V_s \) and oscillating Vωcosωt bias voltage between N and S. It is shown that the conductance as a function of\(\bar V_s \) has a Shapiro-like step at\(\bar V_s \)= ħω/2e. This exists in the case when the spacing between two superconductors largely exceeds the coherence length. It is also shown that the Shapiro step height decreases rapidly when the junction size exceeds the phase breaking length.
