  • Fujii, Masafumi; Maitra, Ayan; Poulton, Christopher; Leuthold, Juerg; Freude, Wolfgang (Optical Society of America, 2006)
    We investigate numerically a non-reciprocal switching behavior in strongly modulated waveguide Bragg gratings (WBGs) having a longitudinally asymmetric stopband configuration. The minimum power predicted for a stable ...
  • Lau, Yiu; Braun, Michael; Hutton, Brian (Institute of Physics, 2001)
    Conventional approaches to image registration are generally limited to image-wide rigid transformations. However, the body and its internal organs are non-rigid structures that change shape due to changes in the body's ...

    The Northern HIPASScatalogue (NHICAT) is the northern extension of the HIPASS catalogue, HICAT. This extension adds the sky area between the declination (Dec.) range of +20 < 8 < +25"30' to HICAT's Dec. range of -900 < ...

    The Northern HIPASS catalogue (NHICAT) is the northern extension of the HIPASS catalogue, HICAT. This extension adds the sky area between the declination (Dec.) range of +2 degrees < delta < +25 degrees 30' to HICAT's Dec. ...
  • Earp, Alan; Smith, Geoff; Franklin, Jim; Mccredie, Geoff (SPIE, 2001)
    Simple quantitative performance criteria are developed for translucent materials in terms of hemispherical visible transmittance, and angular spread of transmitted luminance using a half angle. Criteria are linked to ...
  • Orlic, I.; Siegele, R.; Hammerton, K.; Jeffree, Ross; Cohen, D. (Elsevier Inc, 2003)
    Elevated concentrations of lead were found in Australian free ranging saltwater crocodile (Crocodylus porosus) bone and flesh. Lead shots were found as potential source of lead in these animals. ANSTO s heavy ion nuclear ...
  • 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 ...
  • Schwefel, H; Poulton, Christopher; Wang, L (IEEE/LEOS, 2008)
    A novel and numerically efficient multipole formulation for the calculation of resonances of photonic molecules is presented. Photonic molecules are often modeled as two dimensional coupled dielectric disks. We use the ...
  • Koos, Christian; Jacome, L; Poulton, Christopher; Leuthold, Juerg; Freude, Wolfgang (Optical Society of America, 2007)
    We numerically investigate the band structure and guided modes within arrays of metallic nanowires. We show that bandgaps appear for a range of array geometries and that these can be used to guide light in these structures. ...
  • Guenneau, Sebastien; Poulton, Christopher; Movchan, Alexander (Royal Society, 2003)
    This paper presents analysis of electromagnetic and elastodynamic waves propagating through a doubly periodic array of cylindrical channels in oblique incidence. A new method, based on a multipole scattering approach, has ...
  • Coleman, V; Buda, M; Tan, Hark; Jagadish, Chennupati; Koike, K; Sasa, S; Inoue, M; Yano, M; Phillips, Matt (IOP Publishing Ltd, 2006)
    Implantation with low-energy (80 keV) oxygen ions and subsequent rapid thermal annealing at 800 degrees C are used to induce intermixing in a stack of 19 ZnO/Zn0.7Mg0.3O multiple quantum wells grown oil sapphire by molecular ...
