Abstract
It was shown some time ago that open bi-layered plasmonic nanostructures may support trapped light states with infinite lifetimes. Counterintuitively, here we prove that spatially dispersive effects may relax the material and geometrical conditions required for the formation of embedded eigenstates in plasmonic systems.
