Inverse wave-number-dependent source problems for the Helmholtz equation
Hongxia Guo, Guanghui Hu
This paper is concerned with the multi-frequency factorization method for imaging the support of a wave-number-dependent source function. It is supposed that the source function is…

Imaging a moving point source from multi-frequency data measured at one and sparse observation points (part II): near-field case in 3D
Guanqiu Ma, Hongxia Guo, Guanghui Hu
In this paper, we introduce a frequency-domain approach to extract information on the trajectory of a moving point source. The method hinges on the analysis of multi-frequency near…

Well-posedness and convergence analysis of PML method for time-dependent acoustic scattering problems over a locally rough surface
Hongxia Guo, Guanghui Hu
We aim to analyze and calculate time-dependent acoustic wave scattering by a bounded obstacle and a locally perturbed non-selfintersecting curve. The scattering problem is equivale…
