Identifying defective units in infinite periodic arrays of point sources
Dinh-Liem Nguyen, Nhung H. Nguyen, Thi-Phong Nguyen
This paper focuses on identifying defective units in unbounded periodic arrays of point sources using boundary data. The study is motivated by the noninvasive evaluation of large-s…

Direct sampling methods for isotropic and anisotropic scatterers with point source measurements
Isaac Harris, Dinh-Liem Nguyen, Thi-Phong Nguyen
In this paper, we consider the inverse scattering problem for recovering either an isotropic or anisotropic scatterer from the measured scattered field initiated by a point source.…

The quasi-reversibility method to numerically solve an inverse source problem for hyperbolic equations
Thuy T. Le, Loc H. Nguyen, Thi-Phong Nguyen +1
We propose a numerical method to solve an inverse source problem of computing the initial condition of hyperbolic equations from the measurements of Cauchy data. This problem arise…
