Popis:	Diffraction of a pulsed point source near a hard half-plane cylindrically curved near its edge is analyzed by the geometrical theory of diffraction. Source and receiver are both on the convex side of the curved surface. The solution includes first and second order edge diffracted fields: those of the edge and creeping wave and those of the discontinuity in curvature at the junction between the cylindrical segment and the plane surface. The latter are particularly strong near the reflection boundary, as shown in numerical results for zero offset between a source receiver pair. Creeping waves are calculated across their transition boundary using Fock functions and into the shadow region where they are strong enough to be observed experimentally.
