  • Asatryan, Ara; Botten, Lindsay; Byrne, Michael; Langtry, Timothy; Nicorovici, Nicolae; Mcphedran, Ross; De Sterke, C; Robinson, Peter (American Physical Soc, 2005)
    The conductance of photons in two-dimensional disordered photonic crystals is calculated using an exact multipole-plane wave method that includes all multiple scattering processes. Conductance fluctuations, the universal ...
  • White, Tom; Mcphedran, Ross; De Sterke, C; Botten, Lindsay; Steel, Michael (Optical Society of America, 2001)
  • Bordas, Frederic; Steel, Michael; Seassal, Christian; Rahmani, Adel (Optical Society of America, 2007)
    We study the confinement of low group velocity band-edge modes in a photonic crystal slab. We use a rigorous, three dimensional, finite-difference time-domain method to compute the electromagnetic properties of the modes ...
  • Guenneau Sebastien; Guenneau, Sebastien; Poulton, Christopher; Movchan, Alexander (Elsevier Inc, 2003)
    This paper presents properties of electromagnetic waves propagating through a doubly periodic array of cylindrical channels in oblique incidence. A new method, based on a multipole scattering approach, has been proposed ...
  • Bradby, Jodie; Kucheyev, Sergei; Williams, Jim; Jagadish, Chennupati; Swain, Michael; Munroe, Paul; Phillips, Matthew (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 ...
  • Toth, Milos; Lobo, Charlene; Lysaght, Michael; Vladar, Ae; Postek, Mt (Amer Inst Physics, 2009)
    Many ultraviolet, x-ray and charged particle beam techniques are inhibited by the growth of carbonaceous films caused by cross linking of hydrocarbon contaminant adsorbates. In electron microscopy, such films obscure surface ...
  • Mokkapati, Sudha; Lever, Penelope; Tan, Hark; Jagadish, Chennupati; Mcbean, Katie; Phillips, Matthew (Amer Inst Physics, 2005)
    Selective growth of InGaAs quantum dots on GaAs is reported. It is demonstrated that selective-area epitaxy can be used for in-plane bandgap energy control of quantum dots. Atomic force microscopy and cathodoluminescence ...
  • Wu, Helen; Fitzell, Bob; Samali, Bijan (Australian Acoustical Society, 2005)
    Base isolation is found effective in reducing torsional response of structures with mass eccentricity when subjected to earthquakes. In this study, dynamic characteristics of an eccentric five-storey benchmark model, ...
  • Poulton, Christopher; Mcphedran, Ross; Movchan, Natalia; Movchan, Alexander (Taylor & Francis Ltd, 2010)
    We present converged band diagrams for Bloch-Floquet bending waves in a thin elastic plate containing a square array of circular perforations, using the multipole formulation developed by Movchan et al. (2007) and applied ...
  • Guo, Youguang; Zhu, Jianguo; Zhong, Jin Jiang; Wu, Wei (IEEE-Inst Electrical Electronics Engineers Inc, 2003)
  • Cortie, Michael; Dowd, Annette; Harris, Nadine; Ford, Michael (American Physical Society, 2007)
    We propose a smart nanoparticle, a regulatron, that exploits a cycle of dynamic plasmonic feedback to self-regulate its temperature to a fixed range. One kind of regulatron can be conceived from VO2 and Au; the temperature ...
  • Ton-That, Cuong; Foley, Matthew; Phillips, Matthew; Tsuzuki, Takuya; Smith, Zoe (Elsevier, 2012)
    The crystallographic and optical properties of Mn-doped ZnO nanoparticles prepared by a sol-gel process have been investigated by X-ray diffraction, UV-visible absorption spectroscopy and cathodoluminescence microanalysis. ...
  • Bordas, Frederic; Louvion, Nicolas; Callard, Segolene; Chaumet, Patrick; Rahmani, Adel (American Physical Society, 2006)
    We present a coupled-dipole treatment of radiation dynamics in the weak-coupling regime in a finite three-dimensional photonic crystal structure. The structure is discretized in real space and the self-consistent local ...
  • Chaumet, Patrick; Sentenac, Anne; Rahmani, Adel (American Physical Society, 2004)
    In the coupled dipole method, a three-dimensional scattering object is discretized over a lattice into a set of polarizable units that are coupled self-consistently. Starting from the volume integral equation for the field, ...
  • Chaumet, Patrick; Belkebir, Kamal; Rahmani, Adel (Optical Society of America, 2008)
    We present a time-domain formulation of electrodynamics based on the self-consistent derivation of the electromagnetic field in a linear, dispersive, lossy object via the coupled dipole method.
  • Rahmani, Adel; Chaumet, Patrick; Bryant, Garnett (Optical Society of America, 2002)
    We present a new formulation of the coupled dipole method that accounts for local-field effects and is exact in the long-wavelength limit. This formulation also leads to improved accuracy of the description of light-scattering ...
  • Smith, Geoffrey; Pustovit, Vladimir (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 ...
  • Brownless, John; Mahmoodian, Sahand; Dossou, Kokou; Lawrence, Felix; Botten, Lindsay; De Sterke, C (Optical Society of America, 2010)
    We investigate dispersion curves of coupled waveguides in hexagonal lattices. We find that their coupling coefficients change magnitude and sign along the BZ and that the modes here are no longer odd and even modes.
  • Brownless, John; Mahmoodian, Sahand; Dossou, Kokou; Lawrence, Felix; Botten, Lindsay; De Sterke, C (Optical Society of America, 2010)
    We investigate the modes of coupled waveguides in a hexagonal photonic crystal. We find that for a substantial parameter range the coupled waveguide modes have dispersion relations exhibiting multiple intersections, which ...
