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…

Inverse wave-number-dependent source problems for the Helmholtz equation with partial information on radiating period
Hongxia Guo, Guanghui Hu, Guanqiu Ma
This paper addresses a factorization method for imaging the support of a wave-number-dependent source function from multi-frequency data measured at a finite pair of symmetric rece…
