Acoustic scattering from a rectangular aperture in a thick hard screen

Abstract

Acoustic scattering from a rectangular aperture in a thick hard screen is examined. The Fourier transform is used to represent the scattered wave in the spectral domain and the boundary conditions are enforced to represent a solution in closed form. Numerical computations are performed to illustrate the behavior of the scattered wave from a thick rectangular aperture. The solution is represented in series which are numerically efficient.
