Inverse scattering for three-dimensional random obstacles with multi-frequency data
Zhiqi Sun, Yiwen Lin
The paper develops a Monte Carlo‑based multi‑frequency recursive linearization method to recover the shape and statistical properties of three‑dimensional random acoustic obstacles…
Inverse acoustic scattering for random obstacles with multi-frequency data
Zhiqi Sun, Xiang Xu, Yiwen Lin
We study an inverse random obstacle scattering problems in where the scatterer is formulated by a Gaussian process defined on the angular parameter domain. Equipped…
Random Regularity of the Vlasov-Poisson System with Random Initial Inputs in the Quasineutral Regime
Wenyi Wang, Yiwen Lin
The Vlasov-Poisson system is widely used in plasma physics and other related fields. In this paper, we study the Vlasov-Poisson system with initial uncertainty in the quasineutral…
An inverse random diffraction grating problem for the Helmholtz equation
Zhiqi Sun, Yiwen Lin
This paper investigates the inverse scattering problem of time-harmonic plane waves incident on a perfectly reflecting random periodic structure. To simulate random perturbations a…
