Frequency shift of sources embedded in finite two-dimensional photonic clusters

Asatryan Ara; Botten Lindsay; Nicorovici Nicolae; Mcphedran Ross; De Sterke C (Taylor & Francis, 2006)

The frequency (Lamb) shift and local density of states (LDOS) in two-dimensional photonic crystals composed of a cluster of infinitely long circular cylinders is calculated classically using the radiation reaction ...
Fresnel Formulation For Multi-element Lamellar Diffraction Gratings In Conical Mountings

Camnpbell S; Botten Lindsay; De Sterke C; Mcphedran Ross (Taylor and Francis, 2001)
From Multipole Methods to Photonic Crystal Device modeling

Mcphedran Ross; De Sterke C; Nicorovici Nicolae; Asatryan Ara; Smith Geoff; Langtry Timothy; White Thomas; Botten Lindsay; Fussell David; Kuhlmey Boris (Taylor & Francis, 2006)
Gap-edge asymptotics of defect modes in two-dimensional photonic crystals

Dossou Kokou; Mcphedran Ross; Botten Lindsay; Asatryan Ara; De Sterke C (Optical Society of America, 2007)

We consider defect modes created in complete gaps of 2D photonic crystals by perturbing the dielectric constant in some region. We study their evolution from a band edge with increasing perturbation using an asymptotic ...
Gap-edge asymptotics of defect modes in twodimensional photonic crystals

Dossou Kokou; Mcphedran Ross; Botten Lindsay; Asatryan Ara; De Sterke C (Optical Society of America, 2007)

We consider defect modes created in complete gaps of 2D photonic crystals by perturbing the dielectric constant in some region. We study their evolution from a band edge with increasing perturbation using an asymptotic ...
Gas Cascade Amplification in Ultra-High-Resolution Environmental Scanning Electron Microcopy

Toth Milos; Thiel Bradley; Knowles William (Cambridge Univ Press, 2010)

We describe a feedback mechanism in the gas cascade amplification process used in magnetic immersion lens environmental scanning electron microcopy (ESEM). Feedback dominates gas gain under the conditions typically used ...
Gaseous scintillation detection and amplification in variable pressure scanning electron microscopy

Morgan Scott; Phillips Matthew (American Institute of Physics, 2006)

This work investigates the generation and detection of gaseous scintillation signals produced in variable pressure scanning electron microscopy through electron-gas molecule excitation reactions. Here a gaseous scintillation ...
Gene expression profiling of HUH7-ins Lack of a granulogenic function for Chromogranin A

Lutherborrow Mark; Appavoo Mathiyalagan; Simpson Ann; Tuch Bernard (Landes Bioscience, 2009)

Previously, the insulin producing liver cell line HUH7-ins has been shown to synthesize, store and secrete insulin in response to glucose via secretory granules. The current study characterized the gene expression profile ...
General Characteristics of Localisation in Stratified Media with Randon Loss and Gain

Botten Lindsay; De Sterke C; Mcphedran Ross; Nicorovici Nicolae; Asatryan Ara; Robinson Peter (Kluwer Academic Publishers, 2001)

Localization in multi-layer stratified media with gain and loss is considered. The localization length is studied as a function of wavelength over a wide spectral range, and it is demonstrated that, in many cases, the ...
Generalisation of the transfer matrix formulation of the theory of electron and photon conductance

Botten Lindsay; Asatryan Ara; Nicorovici Nicolae; Mcphedran Ross; De Sterke C (Elsevier Science Bv, 2007)
Generalization of the coupled dipole method to periodic structures

Chaumet Patrick; Rahmani Adel; Bryant Garnett (American Physical Society, 2003)

We present a generalization of the coupled dipole method to the scattering of light by arbitrary periodic structures. This formulation of the coupled dipole method relies on the same direct-space discretization scheme that ...
General theory of three-dimensional radiance measurements with optical microprobes

Fukshansky-Kazarinova N.; Fukshansky L.; Kuhl Michael; Jã¸Rgensen B. (Optical Society of America, 1997)

Measurements of the radiance distribution and ?uence rate within turbid samples with ?ber-optic radiance microprobes contain a large variable instrumental error caused by the nonuniform directional sensitivity of the ...
Generation of highpower terahertz pulses in a prism

Johnston Michael; Whittaker David; Dowd Annette; Davies A.; Linfield Edmund; Li X; Ritchie D (Optical Society of America, 2002)

A compact, high-power emitter of half-cycle terahertz (THz) radiation is demonstrated. The device consists of an epitaxial InAs emitter upon a GaAs prism and produces THz pulses that are 20 times more powerful than those ...
Glycothermal synthesis of assembled vanadium oxide

Fu Haitao; Jiang Xuchuan; Yang Xiaohong; Yu Aibing; Su Dawei; Wang Guoxiu (Springer, 2012)

This study demonstrates a facile but effective glycothermal method to synthesize vanadium oxide nanostructures for gas sensing detection. In this method, sodium orthovanadate was first dispersed and heated in ethylene ...
Graphene-supported SnO2 nanoparticles prepared by a solvothermal approach

Wang Bei; Su Dawei; Park Jinsoo; Ahn Hyojun; Wang Guoxiu (Springer New York LLC, 2012)

SnO2 nanoparticles were dispersed on graphene nanosheets through a solvothermal approach using ethylene glycol as the solvent. The uniform distribution of SnO2 nanoparticles on graphene nanosheets has been confirmed by ...
Green's functions and relative local density of states in two-dimensional lossy structured systems

Nicorovici Nicolae; Mcphedran Ross; Botten Lindsay; Poulton Christopher; Asatryan Ara (Taylor and Francis, 2010)

The local density of states (LDOS) is a function of spatial position and frequency which governs the radiation properties of sources placed within structured optical systems. We show how the enhancement or suppression of ...
Group velocity in lossy periodic structured media

Chen Parry; Mcphedran Ross; De Sterke C; Poulton Christopher; Asatryan Ara; Botten Lindsay; Steel Michael (American Physical Society, 2010)

In lossless periodic media, the concept of group velocity is fundamental to the study of propagation dynamics. When spatially averaged, the group velocity is numerically equivalent to energy velocity, defined as the ratio ...
Growth and Characterization of ZnO Nanoparticles

Tomaszewska-Grzeda A; Lojkowski W; Godlewski Marek; Yatsunenko S; Drozdowicz-Tomsia Krystyna; Goldys Ewa; Phillips Matthew (Polish Academy of Sciences, 2005)

In this work we evaluate structural and optical properties of ZnO nanoparticles grown by wet chemistry method. Light emission properties of these nanoparticles are studied with cathodoluminescence and micro- photoluminescence. ...
Growth-temperature-dependent cathodoluminescence properties of GaSb/GaAs quantum-dot multilayer structures

Drozdowicz-Tomsia Krystyna; Goldys Ewa; Motlan Motlan; Zareie Hadi; Phillips Matthew (American Institute of Physics, 2005)
