Abstract


This paper will describe a new type of subradiant plasmon that can be continuously tuned in 2D arrays of large (> 100 nm) nanoparticles. The arrays support out-of-plane dipolar interactions that suppress radiative decay and amplify local fields. At the subradiant resonance wavelength, the incident light is trapped in the nanoparticle array plane, and accumulated plasmon energy results in strong nano-localized fields on each particle.
