  • White, Tom; Botten, Lindsay; Mcphedran, Ross; De Sterke, C (Optical Soc Amer, 2003)
    A novel design for an ultracompact, high-Q notch-rejection filter is presented, and an analytic expression for the transmission properties is derived. This folded directional coupler shares the properties of a Fabry?Perot ...
  • Wang, Guoming; Ying, Mingsheng (American Physical Soc, 2006)
    We address the problem of unambiguous discrimination among a given set of quantum operations. The necessary and sufficient condition for them to be unambiguously distinguishable is derived in the cases of single use and ...
  • Zhang, Y; Zhu, H; Zhou, Sihai; Ding, S; Lin, Zhi Wei; Zhu, Jianguo (Amer Inst Physics, 2006)
    MgB2 superconducting thin films on Si(111) and Al2O3(0001) substrates were prepared by high vacuum e-beam evaporation and two-step in situ annealing techniques. The precursor films [B(100 angstrom)/Mg(151 angstrom)](6)/Al2O3 ...
  • Zhang, Chengqi; Ying, Mingsheng; Qiao, Bo (American Physical Soc, 2006)
    We discuss the problem of designing unambiguous programmable discriminators for any n unknown quantum states in an m-dimensional Hilbert space. The discriminator is a fixed measurement that has two kinds of input registers: ...
  • Arnold, Matthew; Blaber, Martin; Ford, Michael; Harris, Nadine (Optical Society of America, 2010)
    The position, width, extinction, and electric field of localized plasmon modes in closely-coupled linear chains of small spheres are investigated. A dipole-like model is presented that separates the universal geometric ...
  • Logan, Peter (Addison-Wesley, 1992)
    This book is designed for students studying a first year physics at University.
  • Shahbazi, M; Wang, Xiu-Hong; Shekhar, C; Srivastava, On; Lin, Zhi Wei; Zhu, Jianguo; Dou, Shi (Amer Inst Physics, 2011)
    The magneto-resistance, critical current density, Jc, upper critical field, Hc2, and flux pinning properties of LaFeAsO1 xFx superconductors were investigated systematically by magnetic and magneto-transport measurements ...
  • Lin, Zhi Wei; Lu, Haiwei; Zhu, Jianguo; Zhong, Jin Jiang; Wang, Xiu-Hong; Ding, S (Amer Inst Physics, 2005)
    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 Ara; Sheppard Colin; De Sterke C; Asatryan, Ara; Sheppard, Colin; De Sterke, C (Journal of the Optical Society of America B Optical PhysicsOptical Soc Amer, 2004)
    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 ...
  • White, Tom; De Sterke, C; Botten, Lindsay; Mcphedran, Ross (Optical Society of America, 2005)
  • Servant, Jean-Pierre; Guenneau, Sebastien; Movchan, Alexander; Poulton, Christopher (Kluwer, 2003)
    In this paper, we analyse the propagation of elastodynamic waves in a circular cylinder in the case of oblique incidence. We use a scattering matrix approach and derive an algebraic linear system which allows us to get a ...
  • 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, Zhi Wei; Li, Yuefeng; Zhu, Jianguo; Wang, Xiu-Hong; Dou, Shi; Guo, Youguang; Lei, Gang; Wang, Yi; Phillips, Matthew; Cortie, Michael; Li, Yancheng; Choi, Kyung-Sook; Shi, X. (Amer Inst Physics, 2011)
    Superconductivity has been found in newly discovered iron-based compounds. This paper studies the motion of magnetic vortices in BaFe(1.9)Ni(0.1)As(2) single crystal by means of the magneto-optical imaging technique. A ...
  • Caprarelli, Graziella; Leitch, Evan (Academic Press, 2009)
    In the western hemisphere of Mars Amazonian volcanism from Arsia Mons produced the smooth surfaces of Daedalia Planum and masks older rocks. Close to the southern termination of Daedalia Planum basement rocks are exposed ...
  • Lin, Zhi Wei; Zhu, Jianguo (Institute of Physics Publishing Ltd, 2004)
    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 ...
  • Schmidt, M; Prill Sempere, L; Tyagi, H; Poulton, Christopher; Russell, P (American Physical Society, 2008)
    We report the fabrication of triangular lattices of parallel gold and silver nanowires of high optical quality, with diameters down to 500 nm and length-to-diameter ratios as high as 100,000. The nanowires are supported ...
  • Caprarelli, Graziella; Wang, Bu (Blackwell Publishing Ltd, 2012)
    In this paper we report the results of our investigation of Evros Vallis, a martian late Noachian dendritic valley network centered at similar to 12 degrees E, 12 degrees S. The study area is located SSW of Schiaparelli ...
