Author(s): Mathias Kobylko, Pierre-Eugène Coulon, Abdallah Slablab, Alexandre Fafin, Julien Cardin, Christian Dufour, Arthur Losquin, Mathieu Kociak, Isabelle Monnet, Dominique Mailly, Xavier Lafosse, Christian Ulysse, Enric Garcia-Caurel, and Giancarlo Rizza While three-dimensional arrays of metallic nanoparticles in a dielectric matrix are promising candidates for plasmonic optical components and metamaterials, their fabrication remains challenging, and the types of structures that can be produced by conventional methods are limited. The authors overcome these limitations by using ion-beam irradiation to produce a periodic arrangement of prolate nanoparticles in a symmetric matrix, controlling both particle aspect ratio and orientation. Applications aside, such a structure is an ideal physical model for evaluating and comparing analytical theories and numerical calculations of the plasmonic resonance in metallic nanoparticles.
