A Wiener–Hopf approximation technique for a multiple plate diffraction problem

An approximation method is derived for the computation of the acoustic field between a series of parallel plates, subject to a time periodic incident field. The method is based on the Wiener–Hopf method of factorization, with computations involving orthogonal bases of functions that are analytic in the complex half‐plane.
