Uniqueness in determining binary grating profiles and refractive indices with a single incoming wave
Jianli Xiang, Guanghui Hu
We investigate inverse diffraction problems for penetrable gratings in a piecewise constant medium. In the TE polarization case, it is proved that a binary grating profile together…
Factorization method for inverse time-harmonic elastic scattering with a single plane wave
Guanqiu Ma, Guanghui Hu
This paper is concerned with the factorization method with a single far-field pattern to recover an arbitrary convex polygonal scatterer/source in linear elasticity. The approach a…
PML and high-accuracy boundary integral equation solver for wave scattering by a locally defected periodic surface
Xiuchen Yu, Guanghui Hu, Wangtao Lu +1
This paper studies the PML method for wave scattering in a half space of homogeneous medium bounded by a two-dimensional, perfectly conducting, and locally defected periodic surfac…
The Wigner Function of Ground State and One-Dimensional Numerics
Hongfei Zhan, Zhenning Cai, Guanghui Hu
In this paper, the ground state Wigner function of a many-body system is explored theoretically and numerically. First, an eigenvalue problem for Wigner function is derived based o…
On accelerating a multilevel correction adaptive finite element method for Kohn-Sham equation
Guanghui Hu, Hehu Xie, Fei Xu
Based on the numerical method proposed in [G. Hu, X. Xie, F. Xu, J. Comput. Phys., 355 (2018), 436-449.] for Kohn-Sham equation, further improvement on the efficiency is obtained i…
Factorization method with one plane wave: from model-driven and data-driven perspectives
Guanqiu Ma, Guanghui Hu
The factorization method by Kirsch (1998) provides a necessary and sufficient condition for characterizing the shape and position of an unknown scatterer by using far-field pattern…
