Аннотация:The 2D problem of diffraction by a curved surface with ideal boundary conditions is considered in
terms of the parabolic equation of diffraction theory. A boundary integral equation of Volterra type
in Cartesian coordinates is introduced. Using the latter, the problem of diffraction by a parabola is
analyzed. It is shown that the solution of this problem coincides with the asymptotic solution for
the problem of diffraction by a cylinder obtained by V. A. Fock. The Efficiency of the numerical
solution of the boundary integral equation is demonstrated for diffraction on a perturbation of a
straight boundary.
