From Slow to Superluminal Propagation: Dispersive Properties of Surface Plasmon Polaritons in Linear Chains of Metallic Nanospheroids
Alexander A. Govyadinov, Vadim A. Markel
We consider propagation of surface plasmon polaritons (SPPs) in linear periodic chains (LPCs) of prolate and oblate metallic spheroids. We show that the SPP group velocity can be e…

Active metamaterials: sign of refraction index and gain-assisted dispersion management
Alexander A. Govyadinov, Mikhail A. Noginov, Viktor A. Podolskiy
We derive an approach to define the causal direction of the wavevector of modes in optical metamaterials, which in turn, determines signs of refractive index and impedance as a fun…
