  • Smith, Geoff (SPIE-Soc Photo-Optical Instrumentation Engineers, 2012)
    Nanotechnology, in particular nanophotonics, is proving essential to achieving green outcomes of sustainability and renewable energy at the production scales needed. Nanomaterials enable optimization of optical, opto-electrical, ...
  • Nicorovici, Nicolae; Mcphedran, Ross; Botten, Lindsay; Poulton, Christopher; Asatryan, Ara (Taylor and Francis, 2010)
    The local density of states (LDOS) is a function of spatial position and frequency which governs the radiation properties of sources placed within structured optical systems. We show how the enhancement or suppression of ...
  • Chen, Parry; Mcphedran, Ross; De Sterke, C; Poulton, Christopher; Asatryan, Ara; Botten, Lindsay; Steel, Michael (American Physical Society, 2010)
    In lossless periodic media, the concept of group velocity is fundamental to the study of propagation dynamics. When spatially averaged, the group velocity is numerically equivalent to energy velocity, defined as the ratio ...

  • Poulton, Christopher; Schmidt, Markus; Pearce, G; Kakarantzas, Georgios; Russell, P (Optical Society of America, 2007)
    We study numerically the formation of photonic band gaps and guided "defect" modes within two dimensional arrays of metallic nanowires. Attenuations as low as 1.7 dB/cm are predicted for silver wires at 1550 nm wavelength.
  • Alonso Martin, Hector; Revel, Alex; Huynh, Phuoc (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 ...
  • Fiala, A; Hillier, R; Mallinson, Samuel; Wijesinghe, Hs (Cambridge Univ Press, 2006)
    This paper presents data on turbulent-spot propagation in the hypersonic boundary-layer flow over a blunted cylindrical body. Data are based on the measurement of time-dependent surface heat transfer rates using gauges ...
  • Orlic, I.; Siegele, R.; Menon, D.; Cohen, D.; Jeffree, Ross; Mcphail, D.; Sarbutt, A.; Stelcer, E.; Markich, Scott (Elsevier B.V., 2002)
    Nuclear milli and microprobes at the Australian Nuclear Science and Technology Organisation (ANSTO) were used to determine lead accumulation in native Australian plants and animals. Three species of eucalypt plants ...
  • Morgan, Scott; Phillips, Matt (IOP Publishing Ltd, 2008)
    The bandwidth and contrast of secondary electron ( SE) images obtained using variable pressure scanning electron microscopy are enhanced when a grounded Frisch grid is placed between the SE detecting anode and the negatively ...
  • Botten, Lindsay; Dossou, Kokou; Wilcox, Stuart; Mcphedran, Ross; De Sterke, C; Nicorovici, Nicolae; Asatryan, Ara (International Journal of microwave and optical Technology, 2006)
    We present an exact theory for modelling the modes of two-dimensional photonic crystals with a truly infinite cladding. It builds on our previous implementation of the fictitious source superposition method for simple point ...
  • White, Tom; De Sterke, C; Mcphedran, Ross; Botten, Lindsay (Amer Inst Physics, 2005)
    We report on very high coupling efficiencies into rod-type photonic crystal (PC) slabs with unmodified interfaces. Three-dimensional finite difference time domain simulations show that reflected powers of less than 1.5% ...
  • Cortie, Michael; Kealley, Catherine; Bhatia, Vijay; Thorogood, Gj; Elcombe, Margaret; Avdeev, M (Elsevier Science Sa, 2011)
    The beta-phase of Au(7)Cu(5)Al(4) undergoes a reversible shape-memory phase transformation, however there has been some uncertainty regarding the crystal structure or structures of the parent phase. Here we show that, under ...
  • Du, Haiping; Zhang, Nong (Academic Press Ltd Elsevier Science Ltd, 2007)
    The paper deals with the H-infinity control problem for active vehicle suspension systems with actuator time delay. The time delay for the actuator is assumed as uncertain time-invariant but has a known constant bound. By ...
