Review of seismic inverse scattering migration and inversion
地球与行星物理论评, 2021 With the shifting toward deeper, geologically more complex, and more subtle hydrocarbon reservoirs than before, the exploration of oil and gas resources is becoming more and more difficult.

Scattering and inverse scattering on ACH manifolds [PDF]
Journal für die reine und angewandte Mathematik (Crelles Journal), 2008 We study scattering and inverse scattering theories for asymptotically complex hyperbolic manifolds. We show the existence of the scattering operator as a meromorphic family of operators in the Heisenberg calculus on the boundary, which is a contact manifold with a pseudohermitian structure.

Crab crossing in inverse Compton scattering
Physical Review Accelerators and Beams, 2023 Inverse Compton scattering is a promising x-ray source, very bright, quasi-monochromatic, and compact. In this paper, we present a generalized theory of Compton backscattering in terms of luminosity, suitable for both classical and quantum regimes.

Tracing multiple scattering trajectories for deep optical imaging in scattering media
Nature Communications, 2023 Multiple light scattering hampers imaging objects in complex scattering media. Approaches used in real practices mainly aim to filter out multiple scattering obscuring the ballistic waves that travel straight through the scattering medium.

Subspace-Based Localization and Inverse Scattering of Multiply Scattering Point Targets
EURASIP Journal on Advances in Signal Processing, 2007 The nonlinear inverse scattering problem of estimating the locations and scattering strengths or reflectivities of a number of small, point-like inhomogeneities (targets) to a known background medium from single-snapshot active wave sensor array data is ...

International Journal of Antennas and Propagation, 2020 In this paper, the whale optimization algorithm (WOA) is applied to the inverse scattering of an imperfect conductor with corners. The WOA is a new metaheuristic optimization algorithm. It mimics the hunting behavior of humpback whales.
