Perfectly matched layers for elastodynamics: a new absorbing boundary condition
Weng Cho Chew,Qing Huo Liu +1 more
TL;DR: This paper proves that a fictitious elastodynamic material half-space exists that will absorb an incident wave for all angles and all frequencies and shows two- and three-dimensional computer simulations of the PML for the linearized equations of elastodynamics.
Journal ArticleDOI
The PSTD algorithm: A time-domain method requiring only two cells per wavelength
TL;DR: A pseudospectral time-domain (PSTD) method is developed for solutions of Maxwell's equations that uses the fast Fourier transform (FFT), instead of finite differences on conventional finite-difference–time-domain methods, to represent spatial derivatives.
Journal ArticleDOI
Through-wall imaging (TWI) by radar: 2-D tomographic results and analyses
TL;DR: It has been shown that using multifrequency data high-quality image reconstruction can be achieved with a limited array view.
Journal ArticleDOI
An accurate algorithm for nonuniform fast Fourier transforms (NUFFT's)
Qing Huo Liu,N. Nguyen +1 more
TL;DR: Based on the (m, N, q)-regular Fourier matrix, a new algorithm is proposed for fast Fourier transform (FFT) of nonuniform (unequally spaced) data with accuracy much better than previously reported results with the same computation complexity.
Journal ArticleDOI
Site-specific kondo effect at ambient temperatures in iron-based molecules
Li Gao,Wei Ji,Yibin Hu,Zhihai Cheng,Zongwu Deng,Qing Huo Liu,Nan Jiang,Xiao Lin,Wei Guo,Shixuan Du,Werner A. Hofer,Xincheng Xie,Xincheng Xie,Hong-Jun Gao +13 more
TL;DR: It is shown that for iron phthalocyanine a Kondo temperature in spectroscopic measurements which is well above room temperature is found, and that the signal of the resonance depends strongly on the adsorption site of the molecule on a gold surface.
