摘要：
We study the Josephson effect in S +/- IS +/- junctions made by a two band superconductor with s perpendicular to wave symmetry. We derive the Andreev coefficients for the scattering problem at the junction interface and the temperature dependence of the critical current. We predict various features of the Josephson current for certain values of the second band strengths and tunnel barrier amplitude among which a high temperature pi state coupling, and a pi to 0 transition as the temperature lowers.
