Tunable Localization and Oscillation of Coupled Plasmon Waves in Graded Plasmonic Chains
M. J. Zheng, J. J. Xiao, K. W. Yu
The localization (confinement) of coupled plasmon modes, named as gradons, has been studied in metal nanoparticle chains immersed in a graded dielectric host. We exploited the time…
Localization of electric field distribution in graded core-shell metamaterials
En-Bo Wei, K. W. Yu
The local electric field distribution has been investigated in a core-shell cylindrical metamaterial structure under the illumination of a uniform incident optical field. The struc…
Dynamic polarizability of rotating particles in electrorheological fluids
J. J. Xiao, J. P. Huang, K. W. Yu
A rotating particle in electrorheological (ER) fluid leads to a displacement of its polarization charges on the surface which relax towards the external applied field ,…
Theory of second-harmonic generation in colloidal crystals
J. P. Huang, Y. C. Jian, C. Z. Fan +1
On the basis of the Edward-Kornfeld formulation, we study the effective susceptibility of secondharmonic generation (SHG) in colloidal crystals, which are made of graded metallodie…
Dispersion and transitions of dipolar plasmon modes in graded plasmonic waveguides
J. J. Xiao, K. Yakubo, K. W. Yu
Coupled plasmon modes are studied in graded plasmonic waveguides, which are periodic chains of metallic nanoparticles embedded in a host with gradually varying refractive indices.…
Optical switching in graded plasmonic waveguides
J. J. Xiao, K. Yakubo, K. W. Yu
A new mechanism of longitudinal confinement of optical energy via coupled plasmon modes is proposed in chains of noble metal nanoparticles embedded in a graded dielectric medium, w…
