Abstract
In this talk, I discuss our recent research activity in tailoring the scattering of nanostructures and metamaterials, with an emphasis on plasmonic phenomena. I will discuss unusual nano-optical responses associated with topological features, including embedded eigenstates, knots in the band diagram of arrays of plasmonic particles, and exotic scattering responses and absorption phenomena enabled by temporal variations. While our results in this context are mostly theoretical in nature, during the talk, I will also discuss the influence of loss and a path towards experimental verification of these concepts.
