Abstract

The effect of geometrical parameters on the optical properties of gold and silver nanorods with rounded edges of arbitrary radius has been studied. An analytical expression for calculating the spectral characteristics of the main longitudinal plasmon resonance of such rods, which depends on the length, diameter and radius of the nanorod and the dielectric permittivity of its material and environment, is obtained.
