Dispersion relation of surface plasmon polaritons in non-local materials
Abstract:
Here, I report on a highly nonlocal metamaterial formed by means of a plasmonic nanorod composite. An analytical characterization of the nonlocal optical response of plasmonic nanowire metamaterials is presented. The former enables negative refraction, subwavelength light guiding, and emission lifetime engineering. I analyze the dispersion of optical waves propagating in nanowire composite. Moreover, the nonlocal effective medium approximation for this dispersion is derived. Two cases, i.e., hexagon and rectangular metamaterial unit cells, are considered.
