The magnetic interference pattern in mesoscopic superconducting/normal/superconducting (SNS) Josephson junctions is sensitive to the scattering in the normal part of the system. In this paper we investigate it, generalizing Ishii’s formula for current-phase dependence to the case of normal scattering at NS boundaries in an SNS junction of finite width. The resulting flattening of the first diffraction peak is consistent with experimental data for S-two-dimensional-electron-gas-S mesoscopic junctions. © 2003 The American Physical Society.
