The effects of penetration depth fluctuations in a disordered-regular
superconducting junction are evaluated in the London limit. This confi
guration demonstrates a disorder-proximity effect: the disorder on the
one side of the junction induces pinning potential fluctuations on th
e other side which penetrate a distance of the order of the penetratio
n depth into the regular side. The associated correlation functions an
d critical currents are calculated and discussed.
