Frustration Effect on Penetration Depth in Long Josephson Junctions Between Single- and Multi-band Superconductors.

The Josephson penetration depth in long junctions between single- and multi-band superconductors is considered by taking into account the frustration effects in a multi-band superconducting state. It is shown, using the effective critical current approach, that the Josephson penetration depth in such structures can manifest qualitative features caused by the case of frustration effects in two- and three-band superconductors.
