Abstract

An extended spectral theory of the diffraction approach is used in the investigation of 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, using the method of D.S. Jones (1971), results in a compact representation involving the generalized Fresnel integral, with certain advantages in numerical applications over past representations
