Abstract
We consider periodic arrangements of metal nanostructures and study the effect of periodicity on the localized surface plasmon resonance of the structures within an electrostatic eigenmode approximation. We show that within this limit the collective surface plasmon resonances of the periodic structures can be expressed in terms of superpositions of the eigenmodes of uncoupled nanostructures that exhibit a standing-wave character delocalized across the entire periodic structure. The formalism derived successfully enables the design and accounts for the observation of plasmonic edge states in periodic structures.
