Direct sampling method to inverse wave-number-dependent source problems (part I): determination of the support of a stationary source
Hongxia Guo, Guanghui Hu, Mengjie Zhao
This paper is concerned with a direct sampling method for imaging the support of a frequency-dependent source term embedded in a homogeneous and isotropic medium. The source term i…
Uniqueness in inverse diffraction grating problems with infinitely many plane waves at a fixed frequency
Xiaoxu Xu, Guanghui Hu, Bo Zhang +1
This paper is concerned with the inverse diffraction problems by a periodic curve with Dirichlet boundary condition in two dimensions. It is proved that the periodic curve can be u…
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…
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…
An orthogonalization-free parallelizable framework for all-electron calculations in density functional theory
Bin Gao, Guanghui Hu, Yang Kuang +1
All-electron calculations play an important role in density functional theory, in which improving computational efficiency is one of the most needed and challenging tasks. In the m…
Uniqueness to inverse acoustic scattering from coated polygonal obstacles with a single incoming wave
Guang-Hui Hu, Manmohan Vashisth
It is proved that a connected polygonal obstacle coated by thin layers together with its surface impedance function can be determined uniquely from the far field pattern of a singl…
