Abstract
The diffraction of a short pulse by a one-dimensional metallic rough surface is investigated with the help of a rigorous integral theory. It is numerically shown that the asymptotic behavior of the diffracted field can be exactly deduced from a knowledge of the strongly excited modes. In addition, this study suggests an experimental means to isolate the spatial structure of a localized mode, taking advantage of the different lifetimes of the various modes.
