Abstract:	We study theoretically the Josephson effect in d-wave superconductor/diffusive normal metal/insulator/diffusive normal metal/d-wave superconductor (D/DN/I/DN/D) junctions. This model aims to describe practical junctions in high-TC cuprate superconductors, in which the product of the critical Josephson current (IC) and the normal state resistance (R) (the so-called ICR product) is very small compared to the prediction of the standard theory for clean d-wave superconductor/insulator/d-wave superconductor (DID) junctions. We show that the ICR product in D/DN/I/DN/D junctions can be much smaller than that in DID junctions. The proposed theory describes the behavior of ICR products quantitatively in high-TC cuprate junctions.
