High order methods for acoustic scattering: Coupling Farfield Expansions ABC with Deferred-Correction methods
Vianey Villamizar, Dane Grundvig, Otilio Rojas +1
Arbitrary high order numerical methods for time-harmonic acoustic scattering problems originally defined on unbounded domains are constructed. This is done by coupling recently dev…
Highly accurate acoustic scattering: Isogeometric Analysis coupled with local high order Farfield Expansion ABC
Tahsin Khajah, Vianey Villamizar
This work is concerned with a unique combination of high order local absorbing boundary conditions (ABC) with a general curvilinear Finite Element Method (FEM) and its implementati…
High order local absorbing boundary conditions for acoustic waves in terms of farfield expansions
Vianey Villamizar, Sebastian Acosta, Blake Dastrup
We devise a new high order local absorbing boundary condition (ABC) for radiating problems and scattering of time-harmonic acoustic waves from obstacles of arbitrary shape. By intr…
The DtN nonreflecting boundary condition for multiple scattering problems in the half-plane
Sebastian Acosta, Vianey Villamizar, Bruce Malone
The multiple-Dirichlet-to-Neumann (multiple-DtN) non-reflecting boundary condition is adapted to acoustic scattering from obstacles embedded in the half-plane. The multiple-DtN map…
On the multi-frequency inverse source problem in heterogeneous media
Sebastian Acosta, Sum Chow, James Taylor +1
The inverse source problem where an unknown source is to be identified from the knowledge of its radiated wave is studied. The focus is placed on the effect that multi-frequency da…
