Imaging a moving point source from multi-frequency data measured at one and sparse observation directions (part I): far-field case
Hongxia Guo, Guanghui Hu, Guanqiu Ma
We propose a multi-frequency algorithm for imaging the trajectory of a moving point source from one and sparse far-field observation directions in the frequency domain. The startin…

Direct sampling method to inverse wave-number-dependent source problems (part I): determination of the support of a stationary source
Hongxia Guo, Guanghui Hu, Mengjie Zhao
This paper is concerned with a direct sampling method for imaging the support of a frequency-dependent source term embedded in a homogeneous and isotropic medium. The source term i…

Uniqueness in inverse diffraction grating problems with infinitely many plane waves at a fixed frequency
Xiaoxu Xu, Guanghui Hu, Bo Zhang +1
This paper is concerned with the inverse diffraction problems by a periodic curve with Dirichlet boundary condition in two dimensions. It is proved that the periodic curve can be u…
