The smallest free-electron sphere sustaining multipolar surface plasmon oscillation
K. Kolwas, A. Derkachova, S. Demianiuk
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 t…

Size dependence of multipolar plasmon resonance frequencies and damping rates in simple metal spherical nanoparticles
A. Derkachova, K. Kolwas
Multipolar plasmon oscillation frequencies and corresponding damping rates for nanospheres formed of the simplest free-electron metals are studied. The possibility of controlling p…
