The scattering of sound waves by the edge of a sandwich panel which consists of two thin elastic plates containing a light interior cellular structure is analysed. The Wiener-Hopf method is used to examine the interaction effects of a semi-infinite panel clamped to a semi-infinite rigid screen. One major difficulty is that the presence of two different velocity potentials on either side of the plane y = 0, results in a matrix Wiener–Hopf equation. An approximate solution is given in the asymptotic limit of small values of a parameter ז , which accounts for the perforations.
