Geometry dependence of surface lattice resonances in plasmonic nanoparticle arrays
Geometry dependence of surface lattice resonances in plasmonic nanoparticle arrays
Plasmonic nanoarrays which support collective surface lattice resonances (SLRs) have become an exciting frontier in plasmonics. Compared with the localized surface plasmon resonance (LSPR) in individual particles, these collective modes have appealing advantages such as angle-dependent dispersions and much narrower linewidths. Here, we investigate systematically how the geometry of the …
