A covariance-based reduced-order framework for solving acoustic scattering problems
Shiwei Sun, Hai Zhang, Jinrui Zhang
This paper presents a physics-aware reduced-order method (ROM) for the efficient computation of wave-scattering problems. Standard model order reduction techniques, typically treat…
Spectral Convergence of the Multipole Expansion Method for Acoustic Scattering in Three Dimensions
Jinrui Zhang, Jun Lai
Multiple scattering is a fundamental wave interaction phenomenon in acoustics and electromagnetics. The multipole expansion method (MEM) is the basis of many fast algorithms, such…
A fast solver for many-particle elastic scattering in layered media
Jinrui Zhang, Yixiao He, Jun lai
This paper proposes a fast solver for time-harmonic elastic scattering by multiple particles embedded in layered media, with either Dirichlet or Neumann boundary conditions imposed…
Pulsed heterodyne detection enables fiber-compatible, high-specificity Brillouin biomechanics in intact tissue and the living brain
Zixuan Du, Shuai Yao, Yun Qi +16
Brillouin microscopy provides label-free, three-dimensional mechanical characterization of biological specimens, but current dispersive detection imposes two limits: the fiber back…
Selective focusing of multiple particles in a layered medium
Jun Lai, Jinrui Zhang
Inverse scattering in layered media has a wide range of applications, examples including geophysical exploration, medical imaging, and remote sensing. In this paper, we develop a s…
Singularity swapping method for nearly singular integrals based on trapezoidal rule
Gang Bao, Wenmao Hua, Jun Lai +1
Accurate evaluation of nearly singular integrals plays an important role in many boundary integral equation based numerical methods. In this paper, we propose a variant of singular…
Selective focusing of elastic cavities based on the time reversal far field model
Jinrui Zhang, Jun Lai
This paper is concerned with the inverse time harmonic elastic scattering of multiple small and well-resolved cavities in two dimensions. We extend the so-called DORT method to the…
Fast inverse elastic scattering of multiple particles in three dimensions
Jun Lai, Jinrui Zhang
Many applications require recovering the geometry information of multiple elastic particles based on the scattering information. In this paper, we consider the inverse time-harmoni…
