Uniqueness, stability and algorithm for an inverse wave-number-dependent source problems
Mengjie Zhao, Suliang Si, Guanghui Hu
This paper is concerned with an inverse wavenumber/frequency-dependent source problem for the Helmholtz equation. In two and three dimensions, the unknown source term is supposed t…

Increasing stability for inverse source problem with limited-aperture far field data at multi-frequencies
Ibtissem Ben Aïcha, Guanghui Hu, Suliang Si
We study the increasing stability of an inverse source problem for the Helmholtz equation from limited-aperture far field data at multiple wave numbers. The measurement data are gi…

Increasing stability for inverse acoustic source problems in the time domain
Chun Liu, Suliang Si, Guanghui Hu +1
This paper is concerned with inverse source problems for the acoustic wave equation in the full space R^3, where the source term is compactly supported in both time and spatial var…
