We emphasize that only the first term here can be interpreted in terms of diffracted rays, and the second term, as well as all high-order asymptotic terms not presented in Equation (2.101), have a pronounced wave nature.Īt the boundaries of the reflected waves, the function (2.98) is discontinuous,Īnd compensates the discontinuities in the geometrical optics part of the total field. One can show that away from the boundaries of reflected plane waves, whereġ, the asymptotics (2.98) transforms intoĥ4 Chapter 2 Wedge Diffraction: Exact Solution and Asymptotics As a result we obtain the following asymptotic expression 2.6 Uniform Asymptotics: Extension of the Pauli Technique 53Īccording to Equation (2.73), these integrals are reduced to the Fresnel integrals.
