  • Field profiles for spherical conductive nanoparticles and metallic-shell/dielectric-core nano-composites 
    Schelm Stefan; Smith Geoffrey (Spie-Int Society Optical Engineering, 2004)
    Profiles of the electric field strength |E|2/|Eo|2 for spherical metallic shells on a dielectric core are presented both inside the particle and outside. The dependence of the near-field strength and extent on shell ...
  • Formation and dissociation of hydrogen-related defect centres in Mg-doped GaN 
    Gelhausen Olaf; Phillips Matthew; Goldys Ewa; Paskova Tanja; Monemar Bo; Strassburg M; Hoffmann Axel (Materials Research Society, 2004)
    Moderately and heavily Mg-doped GaN were studied by a combination of post-growth annealing processes and electron beam irradiation techniques during cathodoluminescence (CL) to elucidate the chemical origin of the ...
  • General Characteristics of Localisation in Stratified Media with Randon Loss and Gain 
    Botten Lindsay; De Sterke C; Mcphedran Ross; Nicorovici Nicolae; Asatryan Ara; Robinson Peter (Kluwer Academic Publishers, 2001)
    Localization in multi-layer stratified media with gain and loss is considered. The localization length is studied as a function of wavelength over a wide spectral range, and it is demonstrated that, in many cases, the ...
  • Guided Modes in arrays of metallic nanowires 
    Poulton Christopher; Schmidt Markus; Pearce G; Kakarantzas Georgios; Russell P (Optical Society of America, 2007)
  • Heat Loss and Evaporation Rate from an Agitated Water Tank 
    Alonso Martin Hector; Revel Alex; Huynh Ba (AGH University of Science and Technology Press, 2009)
    ABSTRACT. Experiments have been performed to investigate the heat loss and evaporation rate from an open-top tank of heated water that is also agitated vigorously by air bubbling through it. High consumption of electrical ...
  • The integration of forward light transport and lateral illumination of polymer optical fibre 
    Joseph, E. K; Franklin, J.; Smith, G. B; Deller, C. A (Causal Productions Pty Ltd, 2002)
    Flexible polymer light guides doped with special micro-spheres to combine light leakage and long distance transport are described optically using a simple light distribution model. A constant angular profile of light ...
  • Light trapping in translucent samples and its effect on the hemispherical transmittance obtained by an integrating sphere 
    Roos Arne; Jonsson Jacob; Smith Geoffrey (International Society for Optical Engineering (SPIE), 2003)
    When a beam of light is incident on a translucent sample, a significant fraction of the light is scattered at high angles. Some of this scattered light may be trapped inside the substrate through multiple reflections ...
  • Measurement uncertainty as a threshold concept in Physics 
    Wilson Anna; Akerlind Gerlese; Francis Paul; Kirkup Leslie; Mckenzie Jo; Pearce Darren; Sharma Manju (Uniserve Science, 2010)
    We report on the initial findings of a study aimed at developing ways to address threshold concepts in the design of undergraduate curricula, involving academics in two disciplines (physics and law) from four Australian ...
  • Metal nanowire arrays in photonic crystal fibers 
    Prill Sempere L; Schmidt Markus; Tyagi H; Poulton Christopher; Russell P (IEEE/LEOS, 2008)
    Metallic nanowire arrays are created by pumping molten metal into the hollow channels of silica glass PCF. Measurements show that, at certain wavelengths, the core-guided light couples to leaky surface plasmon modes on the ...
  • Modelling and verification of the electrical properties of organic dielectric monolayers in capacitive configurations 
    Zareie Hadi; Liu Jingquan; Cortie Michael; Muller Karl; Ford Michael (International Society for Optical Engineering (SPIE), 2005)
  • Modelling of complex waveguides structures embedded in photonic crystals 
    White Tom; De Sterke C; Asatryan Ara; Mcphedran Ross; Langtry Timothy; Botten Lindsay (COIN/ACOFT 2003, 2003)
    A rigorous approach is developed for guiding and coupling in complex microstructured waveguides embedded in photonic crystals. The method, based on Bloch modes and generalized Fresnel coefficients, is applied to ...
  • Modelling time reversal experiments in the optical domain 
    Marks Benjamin; Steel Michael; Rahmani Adel (IEEE, 2008)
    We present a rigorous numerical study of the sub-wavelength focusing of electromagnetic waves using a time-reversal mirror, and show that the diffraction limit can be overcome in the optical domain.
  • Nanoporous plasmonic coatings 
    Maaroof Abbas; Gentle Angus; Cortie Michael; Smith Geoffrey (The International Society for Optical Engineering, 2007)
    The electrical and optical properties of mesoporous gold are compared to those of thin porous gold films and a simulated thin film made by randomly distributing voids in gold, until the voids fill 76% of film volume. All ...
  • Nonreciprocal transmission and low-threshold bistability in strongly modulated asymmetric nonlinear WBGs 
    Fujii Masafumi; Takashima Tetsuya; Maitra Ayan; Leuthold Juerg; Freude Wolfgang; Poulton Christopher (Optical Society of America, 2007)
    Nonreciprocal optical bistability is numerically investigated in InGaAsP/InP nonlinear waveguide Bragg gratings having a strong and asymmetric sidewall modulation. Minimum switching power as low as 77 mW is predicted by ...
  • Numerically efficient multipole method for photonic molecules 
    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 ...
