Abstract

Peaks associated to multiple Andreev reflections have been used to identify the number of conduction channels, and their transmitivity in mesoscopic superconducting junctions. We analyze the influence of the detailed shape of each channel, and the number of weak links within it, on the final results. Connexions with the statistical interpretation of conductance histograms is also made.
