  • Nicorovici, Nicolae; Mcphedran, Ross; Botten, Lindsay (Taylor & Francis Ltd, 2011)
    We describe a method for accurate calculation of the Relative Local Density of States (RLDOS) as a function of frequency and position in finite sets of coated cylinders. The RLDOS is important, since it describes the ...
  • Nicorovici, Nicolae; Mcphedran, Ross; Botten, Lindsay (Elsevier, 2010)
    We derive the appropriate form of the relative local density of states (RLDOS) for the two-dimensional Helmholtz equation in a homogeneous lossy medium, and give the corresponding result for the three-dimensional equation. ...
  • Pauc, N.; Phillips, Matt; Aimez, V.; Drouin, D. (American Institute of Physics., 2010)

  • Blaber, Martin; Arnold, Matthew; Ford, Mike (IOP Publishing, 2010)
    Alternative materials are required to enhance the efficacy of plasmonic devices. We discuss the optical properties of a number of alloys, doped metals, intermetallics, silicides, metallic glasses and high pressure materials. ...
  • Fu, Yq; Zhu, Shaoli; Zhou, Xl; Zhou, W; Zhao, W (World Scientific Publ Co Pte Ltd, 2011)
    A plasmonic filter applied invisible regime is proposed. A method using discrete dipole approximation (DDA) to aid design parameters of rhombic Ag nanoparticle array is adopted for the filter design and optimization on the ...
  • Peterson, Vanessa; Hunter, Brett; Ray, Abhi; Aldridge, Laurie (Springer-Verlag, 2002)
    Ordinary Portland-cement clinkers were characterised using neutron and synchrotron powder diffraction. Rietveld analysis was performed using individual as well as combined data. Comparisons were made between phase ...
  • Bishop, James; Lobo, Charlene; Martin, Aiden; Toth, Milos; Ford, Mike; Phillips, Matt (American Physical Society, 2012)
    Models of adsorbate dissociation by energetic electrons are generalized to account for activated sticking and chemisorption, and used to simulate the rate kinetics of electron beam induced chemical vapor deposition (EBID). ...
  • Huyang, George; Canning, John; Petermann, Ingemar; Bishop, David; Mcdonagh, Andrew; Crossley, Maxwell (SpringerOpen, 2013)
    The structure and physical properties of a thin titania sol-gel layer prepared on silicon and silica surfaces were examined. Spectroscopic (FTIR, UV-VIS spectroscopy), refractive index (ellipsometry) and microscopic ...
  • Gou, Xinglong; Li, Rong; Wang, Guoxiu; Chen, Zhi; Wexler, David (Institute of Physics (UK), 2009)
    A simple room-temperature solution chemical route for bulk synthesis of high quality ?- Bi2O3 nanowires has been demonstrated. The nanowires have a diameter of about 50 nm and a length in the range of several to tens of ...
  • Li, Yong Jian; Yang, Qing Xin; Wang, You; Zhu, Jianguo; Lin, Zhi Wei (IEEE, 2013)
    In this paper, core loss features of soft magnetic composite (SMC) material from 5 Hz to 1000 Hz have been properly measured and discussed under alternating and three dimensional (3-D) rotational magnetizations. The ...
  • 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 ...
