The smallest free-electron sphere sustaining multipolar surface plasmon oscillation
نویسنده
چکیده
We study the oscillation frequencies and radiative decay rates of surface plasmon modes of a simple-metal sphere as a function of sphere radius without any assumptions concerning the sphere size. We re-examine within the framework of classical electrodynamics the usual expectations for multipolar plasmon frequency in the so called ”low radius limit” of the classical picture.

Size dependence of multipolar plasmon resonance frequencies and damping rates in simple metal spherical nanoparticles
Multipolar plasmon oscillation frequencies and corresponding damping rates for nanospheres formed of the simplest free-electron metals are studied. The possibility of controlling plasmon features by choosing the size and dielectric properties of the sphere surroundings is discussed. Optical properties of the studied metals are described within the Drude-Sommerfeld model of the dielectric functi...
متن کاملReconciling Theory and Experiment in High-resolution Electron Energy-loss Spectroscopy of Plasmon Modes in Individual Nanostructures
Surface plasmon resonances within metal and hybrid nanostructures result from the oscillation of valence electrons in response to an external field [1]. These resonances can strongly dominate the optical response of such structures, and their characteristics are controlled by the composition and geometry of the material. The ability to predictably control these phenomena is enabling a host of n...
متن کاملThe effect of plasmon field on the coherent lattice phonon oscillation in electron-beam fabricated gold nanoparticle pairs.
By using electron beam lithography, we fabricated pairs of gold nanoparticles with varying interparticle separation. Double-beam femtosecond transient absorption spectroscopy was used to determine the coherent lattice oscillation frequency as a function of the interparticle separation in the presence of the plasmon field excited by the monitoring probe light. We found that the fractional shift ...

This work is a study of the Earths free oscillations considering a merge of solid and liquid model. At the turn of 19th century Geophysicists presented the theory of the free oscillations for a self-gravitating, isotropic and compressible sphere. Assuming a steel structure for an Earth size sphere, they predicted a period of oscillation of about 1 hour. About 50 years later, the free oscillat...
متن کاملCorrigendum: Excitation of dark multipolar plasmonic resonances at terahertz frequencies
We experimentally observe the excitation of dark multipolar spoof localized surface plasmon resonances in a hybrid structure consisting of a corrugated metallic disk coupled with a C-shaped dipole resonator. The uncoupled corrugated metallic disk only supports a dipolar resonance in the transmission spectrum due to perfect symmetry of the structure. However, the dark multipolar spoof localized ...
