Abstract

Scattering of a time harmonic scalar field by a hard, soft, or transparent slender body is calculated. The wavelength is assumed to be long compared to the radius of the body cross section, but of any size compared to the body length. The scattered field is represented as an integral of fields from monopoles and dipoles distributed along the centerline of the body. The strengths of these sources are determined by solving integral equations. Then the field is evaluated for bodies either long or short compared to the wavelength. For long bodies, the results of the geometrical theory of diffraction are obtained and the end diffraction coefficients are determined. For short bodies, the low frequency results are found. © 1986, Acoustical Society of America. All rights reserved.
