In this article, an extension of the finite element technique to the analysis of the acoustic radiation is presented. In the proposed approach, the acoustic domain is split into two parts by an arbitrary artificial boundary enclosing the radiating surface. Then the unbounded medium is discretized wi
We present a finite element model for acoustic scattering from an elastic object situated near (or intersecting) the surface separating two fluid domains, each of semi-infinite extent. The fluid domains are truncated using a perfectly matched layer (PML) formulated as an intrinsic part of the mathem
