Exploring 3D elastic-wave scattering at interfaces using high-resolution phased-array system [PDF]
Scientific Reports, 2022 The elastic-wave scattering at interfaces, such as cracks, is essential for nondestructive inspections, and hence, understanding the phenomenon is crucial.

Wave scattering by discrete breathers [PDF]
Chaos, 2003 We present a theoretical study of linear wave scattering in one-dimensional nonlinear lattices by intrinsic spatially localized dynamic excitations or discrete breathers. These states appear in various nonlinear systems and present a time-periodic localized scattering potential for plane waves.

Smoothed Corners and Scattered Waves [PDF]
SIAM Journal on Scientific Computing, 2016 We introduce an arbitrary order, computationally efficient method to smooth corners on curves in the plane, as well as edges and vertices on surfaces in $\mathbb R^3$. The method is local, only modifying the original surface in a neighborhood of the geometric singularity, and preserves desirable features like convexity and symmetry.

Spectral causality and the scattering of waves
Optica, 2021 Causality—the principle stating that the output of a system cannot temporally precede the input—is a universal property of nature. Here, we show that analogous input-output relations can also be realized in the spectral domain by leveraging the peculiar properties of time-modulated non-Hermitian photonic systems.

Scattering of massless scalar field by charged dilatonic black holes
European Physical Journal C: Particles and Fields, 2020 Wave propagations in the presence of black holes is a significant problem both in theoretical and observational aspects, especially after the discovery of gravitational wave and confirmation of black holes.

EM Scattering From a Simple Water Surface Composed of Two Time-Varying Sinusoidal Waves
IEEE Access, 2020 Some novel phenomena, which cannot be well explained by the traditional Bragg scattering theory, have been observed through the electromagnetic (EM) scattering from a water surface composed of two sinusoidal waves.

A variational principle for the scattered wave [PDF]
The Journal of the Acoustical Society of America, 1988 A Schwinger-type variational principle is presented for the scattered field in the case of scalar wave scattering with an arbitrary field incident on an object of arbitrary shape with homogeneous Dirichlet boundary conditions. The result is variationally invariant at field points ranging from the surface of the scatterer to the farfield and is an ...
