ABSTRACTThe diffraction of a high-frequency plane sound wave by a circular cylinder is investigated when the boundary condition on the cylinder is expressed by means of an equation of the form The special feature of this investigation is that an extended form of the Kirchhoff-Fresnel theory of diffraction is used to find an integral representation for the scattering coefficient. In order to avoid the complicated analysis which would be necessary to evaluate the integrals concerned, the more natural geometrical acoustics approach is used to find the first correction term in the scattering coefficient. Numerical results are given for large and small values of the impedance Z.

We present a nonconventional integral equation approach to the scattering of harmonic waves by a smooth or rough perfectly conducting circular cylinder and by a cylinder with a surface impedance. As an application, the case of a corrugated cylinder is investigated. PACS Nos.: 03.50De, 41.20Jb, 41.60Bq
