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…

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…

Differential Imaging of Local Perturbations in Anisotropic Periodic Media
Thi-Phong Nguyen
We discuss the use of differential sampling method to image local perturbations in anisotropic periodic layers, extending earlier works on the isotropic case. We study in particula…
