  • Feigl, Christopher; Russo, Salvy; Barnard, Amanda (Royal Society of Chemistry, 2010)
    Zinc sulfide (ZnS) nanoparticles are of interest for their luminescent and catalytic properties which are useful in bio-medical, electronic and photovoltaic devices. However, ZnS nanoparticles undergo reversible and ...
  • Attard, D; Huggett, Paul; Moran, Ken; Wuhrer, Ric (Cambridge University Press, 2006)
    A titanium-aluminium composite (TAC) has been produced using a novel vacuum cast process [1, 2] that has potential in biomedical and industrial plant applications. The overall aims of this investigation are to develop an ...
  • Poulton, Christopher; Mueller, Manfred; Freude, Wolfgang (Optical Society of America, 2005)
    We present results from a new method for the solution of electromagnetic scattering from finite sets of two-dimensional cylinders exhibiting sidewall deformations. Our model treats the sidewall deviation as a small ...
  • Mcphedran, Ross; Nicorovici, Nicolae; Botten, Lindsay (IOP Publishing Ltd, 2005)
    We consider sums over the set of positive integers relevant to construction of periodic Green's functions for diffraction gratings and similar problems, and provide a general formula for a combination of Bessel functions ...
  • Toth, Milos; Uncovsky, M; Knowles, William; Baker, F S (Amer Inst Physics, 2007)
    Environmental scanning electron microscopy (ESEM) enables electron imaging of gas-mediated, direct-write nanolithography processes, liquids, and hydrated biomaterials. However, ESEM is limited by poor image quality at gas ...
  • Hsieh, Min-Hsiu; Luo, Zhicheng; Brun, Todd (American Physical Society, 2008)
    We prove a regularized formula for the secret key-assisted capacity region of a quantum channel for transmitting private classical information. This result parallels the work of Devetak on entanglement assisted quantum ...
  • Chaumet, Patrick; Rahmani, Adel; Nieto-Vesperinas, Manuel (American Physical Society, 2002)
    We present a detailed theoretical study of the recent proposal for selective nanomanipulation of nanometric particles above a substrate using near-field optical forces [P.C. Chaumet et al., Phys. Rev. Lett. 88, 123601 ...
  • Hinckley, Brook; Dolman, Kevin; Ray, Abhi; Yeung, Wing; Wuhrer, Ric (Cambridge University Press, 2008)
    High-chromium white cast irons are alloys that are based on the iron-chromium-carbon system and are classified in ISO 21988-2006 as abrasion-resistant cast irons that contain greater than 11% chromium. High-chromium white ...
  • Drouin, Dominique; Pauc, N; Poissant, Patrick; Delample, Vincent; Souifi, Albert; Phillips, Matt (IEEE, 2006)
    The scanning electron microsope (SEM) cna be used to study and characterise a wide variety of materials used in nanoelectronic and photonic applications. Several different techniques make use of this versatile tool. These ...
  • Du, Haiping; Sze, Kam; Lam, James (Academic Press, 2005)
    Semi-active H-infinity control of vehicle suspension with magneto-rheological (MR) damper is studied in this paper. First, an experiment is conducted on an MR damper prototype subjected to cyclic excitation. Then, a ...
  • Kan, Dougal; Botten, Lindsay; Poulton, Christopher; Asatryan, Ara; Dossou, Kokou (Amer Physical Soc, 2011)
    We have developed semianalytical methods that allow us to perform a comprehensive analysis of the surface modes of photonic woodpiles. The surface modes of both finite and semi-infinite woodpiles are characterized using ...
  • Dossou, Kokou; Botten, Lindsay; Poulton, Christopher (Optical Soc Amer, 2013)
    We define the concept of an impedance matrix for three-dimensional (3D) photonic and metamaterial structures relative to a reference medium and show that it satisfies a matrix generalization of the basic algebraic properties ...
  • Botten, Lindsay; Asatryan, Ara; White, Tom; De Sterke, C; Mcphedran, Ross; Langtry, Tim (Optical Soc Amer, 2003)
    e present a semianalytic theory for the properties of two-dimensional photonic crystal waveguides of finite length. For single-mode guides, the transmission spectrum and field intensity can be accurately described by a ...
  • Dossou, Kokou; Botten, Lindsay; Mcphedran, Ross; Poulton, Christopher; Asatryan, Ara; De Sterke, C (American Physical Society, 2008)
    We investigate localized defect states near the edge of a band gap in a two-dimensional photonic crystal. An asymptotic approach based on Green's functions leads to analytical results both for the frequency and for the ...
  • Logan, Peter; Stalker, R.; Mcintosh, M. (IOP PUBLISHING, 1977)
    The radiative energy loss from an argon plasma in a shock tube has been investigated, with emphasis on the role of reabsorption. Electron densities reached values of 1.5*1024 electrons m-3 behind the primary shock, and ...
  • Fujii, Masafumi; Koos, Christian; Poulton, Christopher; Sakagami, I.; Leuthold, Juerg; Freude, Wolfgang (Wiley Interscience, 2006)
