Cooperative electromagnetic interactions between nanoparticles for solar energy harvesting

Opt Express. 2014 May 5;22 Suppl 3:A577-88. doi: 10.1364/OE.22.00A577.


The cooperative electromagnetic interactions between discrete resonators have been widely used to modify the optical properties of metamaterials. Here we propose a general approach for engineering these interactions both in the dipolar approximation and for any higher-order description. Finally we apply this strategy to design broadband absorbers in the visible range from simple n-ary arrays of metallic nanoparticles.
