摘要：

We present a transformation-optics approach which sheds analytical insight into the impact that spatial dispersion has on the optical response of separated dimers of metallic nanowires. We show that nonlocal effects are apparent at interparticle distances one order of magnitude larger than the longitudinal plasmon decay length, which coincides with the spatial regime where electron tunneling phenomena occur. Our method also clarifies the interplay between nonlocal and radiation effects taking place in the nanostructure, yielding the dimer dimensions that optimize its light harvesting capabilities.
