Zusammenfassung:The Josephson current through a two-barrier SISIS tunnel junction has been calculated analytically in the quasiclassical approximation for the microscopic theory of superconductivity. Green’s functions for a SISIS tunnel junction and an expression for the Josephson current through a point contact are obtained. The dependence of the tunnel current on the order parameter phase is determined, and the current dependence on the distance between the barriers is analyzed. The presence of resonance peaks in the Josephson current is demonstrated.
