摘要：

We derive formulas for the calculation of scattering amplitude for plates of arbitrary shape. These formulas are line integrals of the coefficient of the field singularity around the edges of the plate. If this coefficient is obtained from the exact solution of the wave equation, then these formulas give the scattering amplitude exactly. If locally this coefficient is approximated by the coefficient of the field singularity from a half plane, then these formulas give the results obtained by the geometrical theory of diffraction when only singly diffracted rays are considered.
