Near-field enhancement of multipole plasmon resonances in Ag and Au nanowires
(American Chemical Society, 2009-04)
In this paper, we investigate theoretically the electromagnetic field enhancement arising from excitation of silver and gold nanowires (NWs) of finite length, capable of sustaining surface plasmon resonances of different ...
Harmonic demodulation and minimum enhancement factors in field-enhanced near-field optical microscopy
(Wiley Blackwell Publishing, Inc, 2015-01)
Field enhanced scanning optical microscopy (FESOM) relies on the design and fabrication of plasmonic probes which had to provide optical and chemical contrast at the nanoscale. In order to do so, the scattering containing ...
Experimental verification of the spectral shift between near- and far-field peak intensities of plasmonic infrared nanoantennas
(American Physical Society, 2013-03)
Theory predicts a distinct spectral shift between the near- and far-field optical response of plasmonic antennas. Here we combine near-field optical microscopy and far-field spectroscopy of individual infrared-resonant ...
Field margin floral enhancements increase pollinator diversity at the field edge but show no consistent spillover into the crop field: a meta-analysis
(Wiley, 2020)
Conventional intensification of agriculture has reduced the availability of resources for pollinators, reducing their diversity and affecting plant pollination, both in natural habitats and croplands. Field margin floral ...
Enhancement and confinement analysis of the electromagnetic fields inside hot spots
(American Chemical Society, 2009-04)
A novel and easy approach to implement is developed to analyze the degree of convergence, confinement, and enhancement (Γ) of calculated electromagnetic fields generated in plasmonic nanoparticles (NPs) of arbitrary shape. ...
Enhanced gauge symmetry and winding modes in Double Field Theory
(Springer, 2016-03)
We provide an explicit example of how the string winding modes can be incorporated in double field theory. Our guiding case is the closed bosonic string compactified on a circle of radius close to the self-dual point, where ...
The Structure, Energy, Confinement, and Enhancement of Hot Spots between Two Nanoparticles
(American Chemical Society, 2013-03)
Hot spots (HSs) between two nanoparticles (NPs) can be considered the canonical example of plasmonic coupling effects and are able to achieve huge enhancements of signals from molecules in fluorescence and Raman spectroscopy. ...
Actors with Multiple Roles: Pleiotropic Enhancers and the Paradigm of Enhancer Modularity
(Elsevier Science London, 2019-06)
The current paradigm in the field of gene regulation postulates that regulatory information for generating gene expression is organized into modules (enhancers), each containing the information for driving gene expression ...
