Abstract
The optical properties of metallic particles at nanometric scale have raised a great interest in scientific community due to the high promising technological applications such as optical communication and storage or quantum optics1. It is well known that optical properties of metallic nanoparticles are dominated by surface plasmons that are collective electron oscillations at a metal‐dielectric interface which can be exploited to manipulate light. In a metallic nanoparticle these oscillations are confined by the boundaries of the particles, resulting in discrete modes of oscillations (plasmon modes) which can be tuned by shaping the geometry of the nanoparticle. Recently, a detailed analysis of surface plasmons in flat structures1 has allowed classifying plasmon modes in two groups. The first group corresponds to the so‐called edge modes which are localized at the periphery of the nanoparticle. These edge modes are …
