报告摘要：
The inverse source scattering problems, as an important research subject in inverse scattering theory, have significant applications in diverse scientific and industrial areas such as antenna design and synthesis, medical imaging, and optical tomography. Although they have been extensively studied, some of the fundamental questions, such as uniqueness, stability, and uncertainty quantification, still remain to be answered. In this talk, our recent progress will be discussed on the inverse source problems for acoustic, elastic, and electromagnetic waves. The stability will be addressed for the the inverse source problems. We show that the increasing stability can be achieved by using the Dirichlet boundary data at multiple frequencies. The stochastic inverse source scattering problems will also be highlighted.
