  • Rahmani, Adel; Chaumet, Patrick; Bryant, Garnett (Chicago journals, 2004)
    We investigate the influence of local-field effects on the electromagnetic response of a collection of dipoles. We derive the local-field corrected static polarizability for a collection of dipoles in the case of a scatterer ...
  • Mcphedran, Ross; Zucker, Ij; Botten, Lindsay; Nicorovici, Nicolae (Royal Soc, 2008)
    We consider a general class of two-dimensional lattice sums consisting of complex powers s of inverse quadratic functions. We consider two cases, one where the quadratic function is negative definite and another more ...
  • Gentle, Angus; Maaroof, Abbas; Cortie, Michael; Smith, Geoff (SPIE, 2007)
    Vanadium dioxide udergoes a reversible metal-insulator phase transition at about 68 degrees C. Cooatings iof this compound are reflective in the infrared above this temperature, and transmissive or absorptive below it, ...
  • Chaumet, Patrick; Rahmani, Adel (American Physical Society, 2013)
    We present a theoretical and numerical study of the optical binding and optical torque between two Rayleigh particles with arbitrary, complex, scalar dielectric permittivity and magnetic permeability. We use a computational ...
  • Chaumet, Patrick; Rahmani, Adel; Zolla, Frederic; Nicolet, Andre; Belkebir, Kamal (American Physical Society, 2011)
    We study, in time domain, the exchange of momentum between an electromagnetic pulse and a threedimensional, discrete, spherical invisibility cloak.We find that a discrete cloak, initially at rest, would experience an ...
  • 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 ...
  • Blaber, Martin; Arnold, Matthew; Ford, Mike (IOP Publishing, 2009)
    First principles calculations have been used to predict the optical properties for a range of intermetallic compounds for which little or no experimental optical data are currently available. Density functional theory ...
  • Maaroof, Abbas; Cortie, Michael; Smith, Geoff (Iop Publishing Ltd, 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 nanoscale ...
  • 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 ...
  • Liu, Jian; Mcbean, Katie; Harris, Nadine; Cortie, Michael (Elsevier Science Sa, 2007)
    Suspensions of mesoscale gold half-shells of controlled size were produced by microsphere-templated vapour deposition and their optical proper-ties were studied. The transmission spectra of the particles exhibited an ...
  • Maaroof, Abbas; Smith, Geoff (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 ...
  • 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 ...
  • 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 ...
  • Ji, Zhengfeng; Cao, H; Ying, Mingsheng (American Physical Soc, 2005)
    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 ...
  • 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 ...
  • 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 ...
  • Deller, Christine; Franklin, Jim (Australian Institute of Physics, 2005)
    Transparent Refractive Index Matched Micro-particles (TRIMM) in polymer rods are highly efficient light mixers. This paper addressess the problem of estimating the optimum length fr the mixing rods, for a given TRIMM-to-matrix ...
  • 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 a??heater zonea?? into the ends of the tube and ...

    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 ...
