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…
On-surface radiation condition for multiple scattering of waves
Sebastian Acosta
The formulation of the on-surface radiation condition (OSRC) is extended to handle wave scattering problems in the presence of multiple obstacles. The new multiple-OSRC simultaneou…
Recovery of the absorption coefficient in radiative transport from a single measurement
Sebastian Acosta
In this paper, we investigate the recovery of the absorption coefficient from boundary data assuming that the region of interest is illuminated at an initial time. We consider a su…
Time reversal for radiative transport with applications to inverse and control problems
Sebastian Acosta
In this paper we develop a time reversal method for the radiative transport equation to solve two problems: an inverse problem for the recovery of an initial condition from boundar…
