Multiple Fano Interferences in a Plasmonic Metamolecule Consisting of Asymmetric Metallic Nanodimers
In this work, WNCG Prof. Andrea Alù, WNCG student Jing Bai and Prof. Khai Q. Le from Hoa Sen University in Vietnam theoretically explore signatures of plasmonic Fano interferences in a sub-wavelength-plasmonic metamolecule. Consisting of closely packed asymmetric gold nanodimers, these signatures lead to the possibility of generating multiple Fano resonances in the scattering spectrum. This spectral feature is attributed to the interference between bright and dark plasmonic modes sustained by the constituent nanodimers.
