Generation of nondiffracting Bessel beam using digital micromirror device
Lei Gong,Yu-Xuan Ren,Guosheng Xue,Qianchang Wang,Jinhua Zhou,Min-Cheng Zhong,Ziqiang Wang,Yinmei Li +7 more
TL;DR: These observations demonstrate that the DMD offers a simple and efficient method to generate Bessel beams with distinct nondiffracting and self-reconstruction behaviors, and will potentially expand the applications to the optical manipulation and high-resolution fluorescence imaging owing to the unique nondIFFracting property.
Journal ArticleDOI
Strain-mediated 180° switching in CoFeB and Terfenol-D nanodots with perpendicular magnetic anisotropy
Qianchang Wang,Xu Li,Cheng-Yen Liang,Anthony Barra,John P. Domann,Christopher S. Lynch,Abdon E. Sepulveda,Greg P. Carman +7 more
TL;DR: In this article, a micromagnetic and elastodynamic finite element model is used to compare the 180° out-of-plane magnetic switching behavior of CoFeB and Terfenol-D nanodots with perpendicular magnetic easy axes.
Journal ArticleDOI
Strain-mediated spin-orbit torque switching for magnetic memory
Qianchang Wang,John Domann,Guoqiang Yu,Guoqiang Yu,Anthony Barra,Kang L. Wang,Gregory P. Carman +6 more
TL;DR: In this article, the authors present a new approach of field-free deterministic perpendicular switching using a strain-mediated spin-orbit torque (SOT) switching method, where the strain-induced magnetoelastic anisotropy breaks the lateral symmetry and the resulting symmetry-breaking is controllable.
Journal ArticleDOI
Strain-Mediated Spin-Orbit-Torque Switching for Magnetic Memory
Qianchang Wang,John Domann,Guoqiang Yu,Guoqiang Yu,Anthony Barra,Kang L. Wang,Gregory P. Carman +6 more
TL;DR: In this article, a mechanism for deterministic perpendicular switching is simulated, showing that uniaxial anisotropies like strain-induced magnetoelastic anisotropy can break a system's lateral symmetry and yield field-free switching in SOT devices.
Journal ArticleDOI
Prototype system of noninterferometric phase-contrast computed tomography utilizing medical imaging components
Zhongqing Wu,Wenbin Wei,Kun Gao,Gang Liu,G. F. Liu,Hongwei Sun,Jianzheng Jiang,Qianchang Wang,Yalin Lu,Yunzhe Tian +9 more
TL;DR: A prototype grating-based phase-contrast CT system is constructed at the National Synchrotron Radiation Laboratory of the University of Science and Technology of China with medical imaging components that enables a large field of view and fast phase- Contrast CT imaging under medical imaging energies.
