## Abstract The current work sets forth a practical approach to numerically solve twoโdimensional direct acoustic scattering problems from complexly shaped scatterers with severe singularities, such as corners and cusps. First, boundary conforming coordinates are generated. This generation is perfo

โฆ Synopsis
A plane sound wave is incident upon an infinite membrane (or thin elastic plate) that is held fixed along two or more parallel lines. A formally exact solution is found and is investigated in the limiting cases of large and small fluid loading, with emphasis on resonance effects in the latter case.

The multiple scattering in two dimensions of incident plane waves by finite thickness parallel plates is investigated theoretically. The incident wave fronts are perpendicular to the gap between the plates. A boundary element method is used for the calculations. Three distinct scattering phenomena a
In this work a novel third-order direct boundary element method for the Helmholtz equation is presented. The methodology is best understood within the context of the so-called ``ยฎctitious eigenvalues diculty'', introduced by the typical direct boundary integral approach; this problem consists of the
