  • Chaumet, Patrick; Rahmani, Adel; Nieto-Vesperinas, Manuel (American Physical Society, 2002)
    We propose a novel way to trap and manipulate nano-objects above a dielectric substrate using an apertureless near-field probe. A combination of evanescent illumination and light scattering at the probe apex is used to ...
  • Zalipaev, Victor; Movchan, Alexander; Poulton, Christopher; Mcphedran, Ross (Royal Society, 2002)
    A mathematical model has been constructed to describe elastic waves propagating in a two?dimensional solid containing a doubly periodic parallelogram array of circular holes. A multipole expansion method is employed which ...
  • Guenneau, Sebastien; Poulton, Christopher; Movchan, Alexander (Elsevier, 2002)
    This Note is devoted to the analysis of elastic waves conically propagating through a doubly periodic array of cylindrical channels. A new method, based on a multiple scattering approach, has been proposed to reduce the ...
  • Zhang, Nong; Kirpitchenko, Inessa (Academic Press, 2002)
    This paper presents the concept of a vibration control system in which motions of a continuous structure with piezoelectric sensors/actuators can be suppressed (or activated) through transforming mechanical energy to ...
  • Bradby, Jodie; Kucheyev, Sergei; Williams, Jim; Wong-Leung, Jennifer; Swain, Michael; Munroe, Paul; Li, Gang; Phillips, Matt (American Institute of Physics, 2002)
    The mechanical deformation of wurtzite GaN epilayers grown on sapphire substrates is studied by spherical indentation, cross-sectional transmission electron microscopy (XTEM), and scanning cathodoluminescence (CL) monochromatic ...
  • Peterson, Vanessa; Hunter, Brett; Ray, Abhi; Aldridge, Laurie (Springer-Verlag, 2002)
    Ordinary Portland-cement clinkers were characterised using neutron and synchrotron powder diffraction. Rietveld analysis was performed using individual as well as combined data. Comparisons were made between phase ...
  • Kucheyev, Sergei; Toth, Milos; Williams, Jim; Jagadish, Chennupati; Li, Gang; Phillips, Matt (American Institute of Physics, 2002)
    Electrical isolation of n-type GaN epilayers bombarded with MeV light ions is studied by energy dispersive x-ray spectrometry (EDS). We show that the maximum bremsstrahlung x-ray energy (the Duane-Hunt limit) can be used ...
  • Kucheyev, Sergei; Toth, Milos; Williams, Jim; Jagadish, Chennupati; Li, Gang; Phillips, Matt (American Institute of Physics, 2002)
    The influence of ion-beam-produced lattice defects as well as H, B, C, N, O, and Si, introduced by ion implantation, on the luminescence properties of wurtzite GaN is studied by cathodoluminescence spectroscopy. Results ...
  • Kuhlmey, Boris; White, Tom; Renversez, Gilles; Maystre, Daniel; Botten, Lindsay; De Sterke, C; Mcphedran, Ross (Optical Society of America, 2002)
    We describe the numerical verifications of a multipole formulation for calculating the electromagnetic properties of the modes that propagate in microstructured optical fibers. We illustrate the application of this formulation ...
  • White, Tom; Kuhlmey, Boris; Mcphedran, Ross; Maystre, Daniel; Renversez, Gilles; De Sterke, C; Botten, Lindsay (Optical Society of America, 2002)
    We describe a multipole method for calculating the modes of microstructured optical fibers. The method uses a multipole expansion centered on each hole to enforce boundary conditions accurately and matches expansions with ...
  • Pustovit, Vladimir; Smith, Geoff (Elsevier Science, 2002)
    Coupled multipolar interactions between spherical nanoparticles coated with metal nanoshells are shown to yield very different optical behaviour to those between all metal nanoparticles in the same configurations. Controlled ...
  • Toth, Milos; Thiel, Bradley; Donald, Athene; Phillips, Matt (American Institute of Physics, 2002)
    We demonstrate that if charging caused by electron irradiation of an insulator is controlled by a defocused flux of soft-landing positive ions, secondary electron (SE) images can contain contrast due to lateral variations ...
  • Toth, Milos; Craven, J; Thiel, Bradley; Donald, Athene; Phillips, Matt (American Institute of Physics, 2002)
    We report on the properties of electric fields generated as a result of electron irradiation of dielectrics in a low vacuum scanning electron microscope. Individual field components produced by (i) ionized gas molecules ...
  • Bradby, Jodie; Kucheyev, Sergei; Williams, Jim; Jagadish, Chennupati; Swain, Michael; Munroe, Paul; Phillips, Matt (American Institute of Physics, 2002)
    Contact-induced damage has been studied in single-crystal (wurtzite) ZnO by cross-sectional transmission electron microscopy (XTEM) and scanning cathodoluminescence (CL) monochromatic imaging. XTEM reveals that the prime ...
  • Dossou, Kokou; Larochelle, Sophie; Fontaine, Marie (IEEE Publications, 2002)
    The birefringence of an optical fiber resulting from an asymmetry of the index profile is numerically evaluated using a finite-element method with a full-vectorial formulation. Such asymmetric index profiles, assumed to ...
  • Hodgkinson, Ian; Wu, Qi; Arnold, Matthew; Mccall, Martin; Lakhtakia, Akhlesh (Elsevier Inc, 2002)
    A left-handed chiral sculptured thin film (STF) that reflects strongly at the wavelength of the circular Bragg resonance tends to partially convert the handedness of incident LCP (left-circularly-polarized) light to RCP ...
  • Johnston, Michael; Whittaker, David; Dowd, Annette; Davies, A.; Linfield, Edmund; Li, X; Ritchie, D (Optical Society of America, 2002)
    A compact, high-power emitter of half-cycle terahertz (THz) radiation is demonstrated. The device consists of an epitaxial InAs emitter upon a GaAs prism and produces THz pulses that are 20 times more powerful than those ...
  • Johnston, Michael; Corchia, A; Dowd, Annette; Linfield, Edmund; Davies, A.; Mclaughlin, Robert; Arnone, Don; Pepper, Michael (Elsevier, 2002)
    We discuss the origins of the magnetic-field-induced enhancement of terahertz (THz) emission from bulk semiconductor surfaces. The principal effect of the magnetic field is to rotate the THz dipole and hence dramatically ...
  • Godlewski, Marek; Goldys, Ewa; Bottcher, T; Figge, Stephan; Hommel, Detlef; Czernecki, R; Prystawko, P; Leszczynski, M; Perlin, Piotr; Wisniewski, P; Suski, T; Bockowski, M; Grzegory, Izabella; Porowski, Sylvek; Phillips, Matt (Polish Academy of Science, 2002)
    Scanning and spot-mode cathodoluminescence investigations of homo- and hetero-epitaxial GaN films indicate a surprisingly small influence of their microstructure on overall intensity of a light emission. This we explain ...
  • Gauvin, Ranald; Griffin, Brendan; Nockolds, Clive; Joy, David; Phillips, Matt (Wiley, 2002)
    A simple method is described to determine the effective gas path length when incident electrons scatter in the gas above the specimen. This method is based on the measurement of a characteristic x-ray line emitted from a ...
