“…Li et al [18] used the boundary element method (BEM) to model acoustic radiation and scattering from bodies of arbitrary shape in close proximity of an infinite plane that has a general impedance boundary condition. In a series of papers, Gaunaurd and Huang [19][20][21] employed translational addition theorems for spherical wave functions to study acoustic scattering by a hard spherical body near a hard flat boundary, by a thin spherical shell near a free surface and by an ideal air bubble near the sea surface. Bishop and Smith [22] developed a null-field T-matrix formalism to investigate plane-wave scattering from an elastic spherical shell near a sediment boundary with an arbitrary roughness profile.…”

“…It is clear that the proximity of the wall makes the problem more difficult to solve. If the wall is initially idealized as rigid, planar, and of infinite extent, a very simple theoretical device known as the method of images can smoothly take its presence into account [3]- [5], [21]. This method substitutes the original boundary value problem by one with two sources in an unbounded medium (i.e., the original source and the mirror image source).…”

“…References [1] and [2] have each employed distinct analytical methods to examine acoustic scattering of plane compressional waves by two identical rigid and elastic spheres, respectively. The method of images in combination with the translational addition theorems for the spherical wave functions are extensively employed to study acoustic scattering by a hard spherical body near a hard flat boundary [3], by a thin spherical shell near a free (pressure release) surface [4], and by an ideal air-bubble near the sea surface [5]. Axisymmetric acoustic radiation from a spherical source vibrating with an arbitrary, time-harmonic velocity distribution while positioned wholly outside a fluid sphere is examined in [6].…”

“…The most relevant acoustic field quantities are the scattering form-function, the scattered far-field pressure, and the scattered intensity. The standard definition of the form-function amplitude with respect to the real sphere is written as (4) …”

“…Gaunaurd and Huang (2) employed the translational addition theorems for the spherical wave functions to study acoustic scattering by a hard spherical body near a hard flat boundary. They also considered acoustic scattering by a thin spherical elastic shell near a free surface (3) , and by an ideal air-bubble near the sea surface (4) . More recently, Hasheminejad (5) examined acoustic radiation from a spherical surface undergoing harmonic modal vibrations near a locally reacting (finite impedance) planar boundary.…”
