Abstract

Construction of complex nanostructures (metasurfaces) became accessible over the past years due to variety of methods like lithography or deposition of nanoparticles. Rapid development of numerical methods for simulation of light interaction with those metasurfaces allow for design of optical elements that act as geometrical phase elements (GPE), mode filters, topological or chiral converters. We report on systematic approach in the designing of such GPE’s using engineered clusters of nanoparticles (meta-atoms) on a substrate. We study in detail optical properties of such nanoclusters and investigate how individual properties of nanoparticles are influencing the collective response of few selected GPE’s.
