Nonradiating toroidal structures
A. D. Boardman, K. Marinov, N. Zheludev +1
Some basic properties of nonradiating systems are considered. A simple connection is established between the existence of residual electromagnetic potentials and the current densit…
Dispersion properties of non-radiating configurations: Finite-Difference Time-Domain modeling
A. D. Boardman, K. Marinov, N. Zheludev +1
A finite-difference time-domain (FDTD) numerical analysis is used to demonstrate that a toroidal solenoid, coaxial with an electric dipole, is a remarkable non-radiating configurat…
Optical whirlpool near absorbing metallic nanoparticle
M. V. Bashevoy, V. A. Fedotov, N. I. Zheludev
The power-flow lines of light interacting with a metallic nanoparticle, in the proximity of its plasmon resonance, form whirlpool-like nanoscale optical vortices. Two different typ…
Continuous `fish scale' planar electromagnetic meta-material
V. A. Fedotov, P. L. Mladyonov, S. L. Prosvirnin +1
We report on a new type of continuous electromagnetic metal planar meta-material, which resembles a `fish scale' structure. It is highly transparent to electromagnetic radiation th…
Light-induced structural transformations in a single gallium nanoparticulate
B. F. Soares, K. F. MacDonald, V. A. Fedotov +1
In a single gallium nanoparticulate, self-assembled (from an atomic beam) in a nano-aperture at the tip of a tapered optical fiber, we have observed evidence for a sequence of reve…
