Abstract
The problem of high-frequency diffraction by elongated bodies is discussed in this paper. The asymptotics are governed by the elongation parameter, which is the ratio of the longitudinal wave dimensions of the body to its cross-section. The cases of axial incidence and that of incidence at a grazing angle to the axis are considered, and the asymptotics of the far field amplitude are developed. Comparisons with numerical results for a set of test problems show that the leading terms of the new asymptotics provide good approximation with respect to the rate of elongation in a uniform manner. Effects of strong elongation on the RCS are discussed.
