Abstract
We construct shadow creeping waves in the problem of a plane wave diffraction by a smooth axi-ally symmetric prolate body of revolution for both Dirichlet and Neumann boundary conditions. Using Fock's asymptotics as the initial data for the creeping wave amplitude, the theory of residues allows us to present the wave field in the main approximation.
