Abstract
The magnetic-field dependence of the critical current I-c(H) is consid ered for a short Josephson junction with the critical current density j(c) alternating along the tunnel contact. Two model cases, periodic a nd randomly alternating j(c), are treated in detail. Recent experiment al data on I-c(H) for grain-boundary Josephson junctions in YBa2Cu3Ox are discussed.
