Abstract :
We discuss the axisymmetrical diffraction problem for a strongly elongated convex and smooth scatterer in shortwave approximation where the classical method of parabolic equation fails. To overcome that difficulty we propose a new boundary layer in the light-shadow zone and consider in more details the matching of asymptotics in the illuminated part of that zone.
