  • Analysis of diffraction gratings by using an edge element method 
    Dossou, K. (Optical Society of America, 2005)
    Typically the grating problem is formulated for the TE and TM polarizations, respectively, by using the electric and magnetic fields aligned with the grating wall and perpendicular to the plane of incidence and this leads ...
  • Analytic properties of photonic crystal superprism parameters 
    Steel Michael; Zoli Rossella; Grillet Christian; Mcphedran Ross; De Sterke C; Norton Andrew; Bassi Paolo; Eggleton Benjamin (American Physical Society, 2005)
    We study the analytic properties of the photonic crystal superprism resolution parameters p, q, and r introduced previously by Baba and Matsumoto fAppl. Phys. Lett. 81, 2325 s2002dg, which characterize the potential ...
  • Ancilla-Assisted Discrimination Of Quantum Gates 
    Chen Jianxin; Ying Mingsheng (Rinton Press, Inc, 2008)
    The intrinsic idea of superdense coding is to find as many gates as possible such that they can be perfectly discriminated. In this paper, we consider a basic scheme of discrimination of quantum gates, called ancilla-assisted ...
  • Anderson Localization Of Classical Waves In Weakly Scattering Metamaterials 
    Asatryan Ara; Gredeskul Sa; Botten Lindsay; Byrne Michael; Freilikher Vd; Shadrivov Iv; Mcphedran Ross; Kivshar Y (Amer Physical Soc, 2010)
    We study the propagation and localization of classical waves in one-dimensional disordered structures composed of alternating layers of left-and right-handed materials (mixed stacks) and compare them with structures composed ...
  • Anticipatory Biomimetic Middleware 
    Chaczko Zenon; Klempous Ryszard (AIP Conference Proceedings, 2010)
    Anticipatory, multi-agents based and biology inspired middleware for resource constrained systems such as the sensornets is able to provide infrastructure oriented services with anticipatory system properties such as: (1) ...
  • Antireflection coatings for two-dimensional photonic crystals using a rigorous impedance definition 
    Lawrence Felix; Botten Lindsay; Dossou Kokou; De Sterke C (American Institute of Physics, 2008)
    We show that no consistent scalar definition of impedance is generally possible for photonic crystals. Instead, we present a rigorous semianalytic matrix definition of impedance for square lattice photonic crystals, defined ...
  • Any 2 Circle Times N Subspace Is Locally Distinguishable 
    Yu Nk; Duan Runyao; Ying Mingsheng (Amer Physical Soc, 2011)
    A subspace of a multipartite Hilbert space is said to be locally indistinguishable if any orthonormal basis of this subspace cannot be perfectly distinguished by local operations and classical communication. Previously it ...
  • The apparent optical indices of spongy nanoporous gold 
    Smith Geoffrey; Cortie Michael; Maaroof Abbas (Australian Institute of Physics, 2005)
    Very thin spongy nanoporous gold films have a unique nanostructure and hence unusual properties. Our interest in these materials is also due to their wide range of potential applications [1,2]. An optical study for such ...
  • An Applicable GSM Network Model for Networking in Rural Environment 
    Li Yang; Agbinya Johnson; Chan H. (UTSePress, 2006)
    Wide rural areas are often short of basic communication facilities and suffer from harsh geographic and climatic environments. Wireless networks which offer ease of operation and low maintenance cost appears to be a ...
  • The application of gold surface and particles in nanotechnology 
    Ford Michael; Masens Carl; Cortie Michael (World Scientific Publishing Company, 2006)
    Gold is widely used in nanotechnology, for example as a substrate in forming self-assembled monolayers or as nanoparticles for their unique optical and chemical properties. In this paper we give an overview of the ...
  • Application of Petri net in development of finite element analysis package for electromagnetic fields 
    Qiu Jie; Li Q; Zhu Jianguo; Wang Semyung; Wang Shuhong (Institute of Electrical and Electronics Engineers, 2006)
    In this paper, Petri net is applied in the description of a parameterized finite element (FE) geometric modeling, which can enable the user to implement quick and easily dimensional changes, and then invoke a repetitive ...
  • Application of small-angle scattering to study the effects of moisture content on a native soy protein 
    Kealley Catherine; Elcombe Margaret; Wuhrer Richard; Gilbert Ep (Blackwell Publishing, 2008)
    The nano-and microstructure of glycinin, a soybean protein, has been investigated as a function of moisture for moisture contents between 4 and 21 wt%. Glycinin exhibits peaks in the small-angle region whose positions show ...
  • An approach to the uniform dispersion of a high volume fraction of carbon nanotubes in aluminum powder 
    Jiang Lin; Fan Genlian; Li Zhiqiang; Chen Zhixin; Zhang Di; Kai Xizhou; Humphries Samuel; Heness Gregory; Yeung Wing (Pergamon, 2011)
    A slurry based process was developed to achieve the uniform dispersion of a high volume fraction of carbon nanotubes (CNTs) in aluminum powder. Al powder was subjected to surface modification to introduce a hydrophilic ...
  • Are you being serviced? promoting quality service teaching 
    Kirkup Leslie; Mather Glyn; Wood Leigh; Logan Peter (Uniserve Science, 2003)
  • Asymptotics of Photonic Band Structures for Doubly-Periodic Arrays 
    Poulton Christopher; Mcphedran Ross; Nicorovici Nicolae; Botten Lindsay; Movchan Alexander (Kluwer Academic Publishers, 2001)
    We examine the allowed modes of polarized electromagnetic waves moving through a doubly periodic material with a cermet topology. We present analytical results for the dispersion relations in two cases; firstly when the ...
