The paper is a direct extension of paper [5] devoted to exploration of the Fock problem in the 3D case. The propagation of the creeping waves in the shadow area of the diffraction obstacle is studied. The creeping waves stem from the reflected wave in the solution of the problem in a vicinity of the light-shadow boundary on the surface of the diffracting obstacle and then they are prolonged into the shadow area. The initial data for the prolongation procedure are the main results of the paper. Bibliography: 7 titles.
