Abstract
Since the advent of all-dielectric nonlinear nanoantennas (NAs), the multipolar Mie decomposition has represented the reference tool to model and analyse their radiation pattern [1]. If on the one hand this is a standard and trusted approach, on the other hand it fails to provide simple rules for the inverse design whenever the nanoantenna shape is not spherical or spheroidal, so that one needs to resort to full numerical analysis [2]. This is all the more true when dealing with arrays, where the coupling among adjacent NAs adds further complexity.File in questo prodotto:
