6. Diffraction ffect of Josephson junction. Consider a junction of rectangular crosssection with a magnetic field B applied in the plane of the junction, normal to an edgeof width te. Let the thickness of the junction be T. Assume for convenience that thephase difference of the two superconductors is m2 when B 0. Show that the decurrent in the presence of the magnetic field issin(uTBellic)J-Jo(wTBelhe)

Given Magnetic field = B Width = w Thickness = T

Diffraction effect of Josephson junction. Consider a junction of rectangular cross section with a magnetic field B applied in the plane of the junction, normal to an edge of width tw.
