Abstract
A new concept of a nonlinear plasmonic nanoantenna with self-tunable scattering pattern (indicatrix) is suggested. It is shown that the onset of modulational instability in a nanoantenna consisting of two identical nonlinear metallic nanoparticles results in dynamic energy exchange between the eigenmodes of the nanodimer, accompanied by periodic rotation and switching of the scattering pattern. Such a nanoantenna features a wide scanning sector, a relatively low working threshold, and a short response time. This makes it attractive for applications in nanophotonics and biology.
