We have generalized the scattering{endash}matrix theory of multiple Andreev reflections in mesoscopic Josephson junctions to the multiple-mode case, and applied it to short superconductor{endash}normal-metal{endash}superconductor (SNS) junctions with diffusive electron transport. Both the dc and ac current-voltage characteristics are analyzed for a wide range of bias voltages V. For voltages smaller than the supeconducting gap the dc differential conductance of the SNS junction is predicted to diverge as 1/{radical}(V). thinsp {copyright} {ital 1997} {ital The American Physical Society}
