“…Some recent investigations were conducted to reveal the influence of the impedance on the diffraction by curved surfaces. Serbest considered the problem of diffraction by a nonperfectly conducting spherical cap for the special case where the surface impedances of the convex and concave faces, say Z1 and Z,, satisfy the condition Z , + Z2 = 0, which implies that Z , = -Z2 = i6 where 6 is a positive real constant [8]. On the other hand, circular cylindrical sheets with equal and different face impedances have been treated by Buyiikaksoy and Uzgoren [9]- [12].…”

A bstract-The construction of a high-frequency solution in the geometrical theory of diffraction (GTD) format for the generation of edge-diffracted space rays and edge-excited surface waves by an electromagnetic wave normally incident on the edge of a curved impedance strip is discussed. The transformation coefficients necessary for the analysis of the diffraction on curved surfaces with equal or vanishing face impedances are tabulated in a form appropriate for numerical applications. The procedure for evaluating the diffracted field excited by the edge of a cylindrically curved strip, which can be associated with a reflector antenna or an aperture on a curved surface, is presented for both perfectly and nonperfectly conducting cases.
