  • Optical forces in time domain on arbitrary objects 
    Chaumet Patrick; Belkebir Kamal; Rahmani Adel (American Physical Society, 2010)
    We develop a general theoretical and computational framework to describe, in time domain, the exchange of momentum between light and arbitrary three-dimensional objects. Our fonnulation can be used to study the time evolution ...
  • Optical properties of intermetallic compounds from first principles calculations: a search for the ideal plasmonic material 
    Blaber Martin; Ford Michael; Arnold Matthew (IOP Publishing, 2009)
  • Optical properties of mesoporous gold films 
    Maaroof Abbas; Cortie Michael; Smith Geoffrey (Institute of Physics Publishing, 2005)
    Mesoporous gold thin films on glass substrates were fabricated by sputtering of AuAl2 precursor films followed by a de-alloying etch. The resulting sponge-like Au films have very high internal surface area due to ...
  • Optical properties of polycrystalline metallic films 
    Sotelo, J.; Ederth, J.; Niklasson, G. (American Physical Society, 2003)
    We extend the Mayadas and Shatkes’s approach [Phys. Rev. B 1, 1382 (1970)] to study the optical properties of polycrystalline metal thick films in the visible and far infrared range of the spectrum. We show that in ...
  • Optical Properties Of Suspensions Of Gold Half-shells 
    Mcbean Katie; Harris Nadine; Liu Jian; Cortie Michael (Elsevier Science Sa, 2007)
  • Optical response in nanostructured thin metal films with dielectric over-layers 
    Smith Geoffrey; Maaroof Abbas (Elsevier, 2004)
    Thin metal films which contain nano-size pores yield higher than expected transmittance and larger than expected times for transmission of near infra red radiation. An optically equivalent layer with complex refractive ...
  • Optical trapping and manipulation of nanoobjects with an apertureless probe 
    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 ...
  • Optical Trapping near a Photonic Crystal 
    Rahmani Adel; Chaumet Patrick (Optical Society of America, 2006)
    We show that the photonic confinement induced by a photonic crystal can be exploited to trap nanoparticles. As demonstrated by the recent advances in the design and fabrication of photonic crystals slab structures, total ...
  • Optimal Conclusive Discrimination Of Two States Can Be Achieved Locally 
    Cao H; Ji Zhengfeng; Ying Mingsheng (American Physical Soc, 2004)
    This paper constructs a local operation and classical communication protocol that achieves the global optimality of conclusive discrimination of any two pure states with arbitrary a priori probability. This can be interpreted ...
  • Optimal Dense Coding With Arbitrary Pure Entangled States 
    Feng Yuan; Duan Runyao; Ji Zhengfeng (American Physical Soc, 2006)
    We examine dense coding with an arbitrary pure entangled state sharing between the sender and the receiver. Upper bounds on the average success probability in approximate dense coding and on the probability of conclusive ...
  • Optimal Simulation Of A Perfect Entangler 
    Yu Nk; Duan Runyao; Ying Mingsheng (Amer Physical Soc, 2010)
    A2 circle times 2 unitary operation is called a perfect entangler if it can generate a maximally entangled state from some unentangled input. We study the following question: How many runs of a given two-qubit entangling ...
  • Optimising the length of doped polymer light mixers 
    Deller Christine; Franklin James (Australian Institute of Physics, 2005)
    Transparent Refractive Index Matched Micro-particles (TRIMM) in polymer rods are highly efficient light mixers. This paper addresses the problem of estimating the optimum length for the mixing rods, for a given TRIMM-to-matrix ...
  • Optimization of a Graphite Tube Blackbody Heater for a Thermogage Furnace 
    Chahine Khaled; Ballico Mark; Reizes John; Madadnia Jafar (Springer Netherlands, 2008)
    Design modifications are presented for a 289-mm long, 25.4-mm inner diameter blackbody heater element of a 48 kW Thermogage blackbody furnace, based on (i) cutting a small â¿¿heater zoneâ¿¿ into the ends of the tube and ...
  • Optimization of a Graphite Tube Blackbody Heater for a Thermogage Furnace

  • Optimization of nonlinear dispersive APML ABC for the FDTD analysis of optical solitons 
    Fujii Masafumi; Omaki N.; Tahara M.; Sakagami I.; Poulton Christopher; Freude Wolfgang; Russer P. (IEEE Publications, 2005)
    We have investigated the parameter optimization for the nonlinear dispersive anisotropic perfectly matched layer (A-PML) absorbing boundary conditions (ABCs) for the two- and the three-dimensional (2D and 3D) finite-difference ...
  • Optimizing the triggering mode for stable operation of a pulsed cathodic arc deposition system 
    Gan Bee; Bilek Marcela; Mckenzie David; Swift Paul; Mccredie Geoffrey (Institute of Physics Publishing, 2003)
    In order to deposit fine structures such as nanoscale multilayers using a pulsed cathodic arc, it is necessary to ensure that the deposition per pulse is stable over a large number of pulses. We compare the deposition ...
  • Ordovician conodonts from the Watonga Formation, Port Macquarie, northeast New South Wales 
    Och David; Percival Ig; Leitch Evan (Linnean Society New South Wales, 2007)
