Transformation-optics description of nonlocal effects in plasmonic nanostructures.
We develop an insightful transformation-optics approach to investigate the impact that nonlocality has on the optical properties of plasmonic nanostructures. The light-harvesting performance of a dimer of touching nanowires is studied by using the hydrodynamical Drude model, which reveals nonlocal resonances not predicted by previous local calculations. Our method clarifies the interplay betwee...
متن کاملSize-Dependent Forced Vibration Analysis of Three Nonlocal Strain Gradient Beam Models with Surface Effects Subjected to Moving Harmonic Loads
The forced vibration behaviors are examined for nonlocal strain gradient nanobeams with surface effects subjected to a moving harmonic load travelling with a constant velocity in terms of three beam models namely, the Euler-Bernoulli, Timoshenko and modified Timoshenko beam models. The modification for nonlocal strain gradient Timoshenko nanobeams is exerted to the constitutive equations by exc...
متن کاملDark field nanoparticle tracking analysis for size characterization of plasmonic and non-plasmonic particles
Dark field microscopy is a widely unknown method to measure the particle size distribution of diffusing nanoparticles by particle tracking. Here we demonstrate that by using the surface plasmonic resonance of Au nanoparticles, size differences of ca. 20 nm can be identified within the particle size distribution. For that purpose, we developed a software tool which helps to analyze color videos ...
متن کاملNonlocal Particles as Strings
We find nonlocal particle theories with two dimensional conformal symmetry, including examples equivalent to the bosonic open string and closed string. This work provides a new approach to construct solvable consistent backgrounds in string theory.
متن کاملSize-dependent Optical Response of Magneto-plasmonic Core-shell Nanoparticles
Functional properties tunability prospect of multi-layered and multi-metallic nanoparticles with respect to their emerging applications has always been the area of attraction. Magnetoplasmonic nanoparticles (MPNPs) present the possibility to exhibit their tuneable magnetic and optical properties with broad applications in magnetic resonance imaging (MRI), cancer therapy, photovoltaic solar cell...
