Control of near-field radiative heat transfer via surface phonon-polariton coupling in thin films
(Springer Business+Media, 2011-06)
The possibility of controlling near-field radiative heat transfer with the use of silicon carbide thin films supporting surface phonon–polaritons in the infrared spectrum is explored. For this purpose, the local density ...
Low-loss optical switch using Brewster angle
(IEEE, 2011)
Fabrication and actuation errors of submicron silicon waveguide optical switches are reported to remain within sub-100 nm ranges. These errors cause high loss ruining the optical performance of the switches at the on-state. ...
Localized radiative energy transfer from a plasmonic bow-tie nano-antenna to a magnetic thin film stack
(Springer Business+Media, 2011-06)
Localized radiative energy transfer from a near-field emitter to a magnetic thin film structure is investigated. A magnetic thin film stack is placed in the near-field of the plasmonic nano-antenna to utilize the evanescent ...
Thermal impacts on the performance of nanoscale-gap thermophotovoltaic power generators
(IEEE, 2011-06)
The thermal impacts on the performance of nanoscale-gap thermophotovoltaic (nano-TPV) power generators are investigated using a coupled near-field thermal radiation, charge, and heat transport formulation. A nano-TPV device ...
The semileptonic B to K1(1270, 1400) decays in QCD sum rules
(IOP Publishing, 2011)
We analyze the semileptonic rare decays of the B meson to K1(1270) and K1(1400) axial vector mesons. The B → K1(1270, 1400)_+_− decays are significant flavor-changing neutral current decays of the B meson. These decays are ...
Effect of commercial purity levels on the mechanical properties of ultrafine-grained titanium
(Elsevier, 2011-03-15)
Two grades of commercial purity (CP) titanium (grades 2 and 4) were processed using equal-channel angular extrusion (ECAE) at 300 ◦C and 450 ◦C, respectively. The processing temperatures were the minimum temperatures at ...
Engineering with and for light absorption and scattering: a quarter century of experimental research at RTL
(Accademia Peloritana dei Pericolanti, 2011)
Characterization of particles requires detailed understanding of light interaction with homogeneous/inhomogeneous and regular/irregular shaped particles, or fractallike structures, within optically thin or thick media. ...
Discrete dipole approximation of gold nanospheres on substrates: considerations and comparison with other discretization methods
(AAPP Physical, Mathematical, and Natural Sciences, 2011)
We embark on this preliminary study of the suitability of the discrete dipole approximation with surface interaction (DDA-SI) method to model electric field scattering from noble metal nano-structures on dielectric substrates. ...
Discrete-dipole approximation with surface interaction: computational toolbox for MATLAB
(Elsevier, 2011-07)
We describe a MATLAB toolbox that utilizes the discrete-dipole approximation (DDA) method for modelling light interaction with arbitrarily-shape scatterers in free space as well with planar surface interaction (DDA-SI). ...
T-matrix method for modelling optical tweezers
(Taylor & Francis, 2011)
We review the use of the T-matrix description of scattering, or the T-matrix method, for the calculation of optical forces and torques, especially for the computational modelling of optical tweezers. We consider both simple ...
