Abstract
A problem of acoustic wave scattering from two circular apertures in a thic k hard plane is solved. The Hankel transform and mode matching is used to r epresent the scattered held in rapidly convergent series. The reflection co efficient, transmission coefficient, and far-zone field are rigorously deri ved and presented in numerically efficient forms. Numerical computations ar e performed to illustrate scattering behaviors in terms of aperture geometr y. (C) 2000 Acoustical Society of America. [S0001-4966(00)01705-7].
