摘要：
An extended spectral theory of diffraction approach is employed in the investigation of the double edge diffraction in the near-field region of a parallel wedge geometry illuminated by a cylindrical wave. A high frequency approximation can be formulated in terms of a canonical double stationary phase integral. A uniform asymptotic reduction of the latter, employing Jones' method, results in a compact representation involving the generalized Fresnel integral, with certain advantages in numerical applications over past representations.
