  • Lin, Z; Lu, H; Zhu, J; Zhong, J; Wang, X; Ding, SY (Amer Inst Physics, 2005-01)
    A three-dimensional (3D) magnetic property testing system has been completed and successfully used to measure 3D hysteresis loci of soft magnetic material. This paper presents the techniques to characterize soft magnetic ...
  • Asatryan, AA; Sheppard, CJ; de Sterke, CM (Optical Soc Amer, 2004-01)
    We present a fast and accurate method to calculate the vector-field distribution of a focused Gaussian beam. This method is applied to calculate the second harmonic that is generated by such a beam from a sample in the ...
  • Lin, Zhi Wei; Zhu, Jianguo; Zhong, Jin Jiang; Johansen, T; Wang, Xiu-Hong; Yu, Wen (Amer Inst Physics, 2007)
    Attractive features of soft magnetic composites (SMCs) are high resistivity, isotropic three-dimensional flux behavior, and easy compression into the complicated shapes required in electromagnetic devices. Comprehensive ...
  • Lin, ZW; Li, YJ; Zhu, JG; Wang, XL; Dou, SX; Guo, YG; Lei, G; Wang, Y; Philips, M; Cortie, M; Li, YC; Choi, K-Y; Shi, X (2011-04-01)
    Superconductivity has been found in newly discovered iron-based compounds. This paper studies the motion of magnetic vortices in BaFe1.9Ni 0.1As2 single crystal by means of the magneto-optical imaging technique. A series ...
  • Lin, ZW; Zhu, JG (2004-09)
    To investigate the magnetic properties of electrical contact between the superconducting filaments in a multifilament tape, this paper studies the vortex motion across a simpler planar model of the tape, namely an array ...
  • Feng, Y; Duan, R; Ying, M (American Physical Soc, 2004-01)
    We determine all 2x2 quantum states that can serve as useful catalysts for a given probabilistic entanglement transformation, in the sense that they can increase the maximal transformation probability. When higher-dimensional ...
  • Duan, R; Shi, Y (2009-11-05)
    For a multipartite quantum system of the dimension $d_1\otimes d_2\otimes... d_n$, $d_1\ge d_2\ge...\ge d_n$, is there an entangled state {\em maximum} in the sense that all other states in the system can be obtained from ...
  • Lavan, D; Hogg, SW; Wolfe, J (Australian Acoustical Society, 2003-01)
    Bell plates are polygonal plates which, when held in the hand and struck with a beater, produce an initial transient followed by a sustained, pure tone. The presence of the sustained tone depends sensitively on the shape. ...
  • Meijer, EJ; Armstrong, NG; Yeung, WY (SciTec Publications Ltd, 2006-01)
    This study is to investigate the crystallite developemtn in nanostructured aluminium using x-ray line broadening analysis. Nanostructured aluminium was produced by equal channel angular extrusion at room temperature to a ...
  • Yan, M; Shao, KR; Hu, X; Guo, Y; Zhu, J; Lavers, JD (IEEE-inst Electrical Electronics Engineers Inc, 2007-01)
    In this paper, a novel and normalized Z-transform-based finite-difference time-domain (ZTFDTD) method is presented for simulating the interaction of the electromagnetic (EM) wave with unmagnetized plasma. The 2-D ZTFDTD ...
