We propose a scheme to obtain a low-loss propagation of Airy surface plasmon polaritons (SPPs) along the interface between a dielectric and a negative-index metamaterial (NIMM). We show that by using the transverse-magnetic mode and the related destructive interference effect between electric and magnetic absorption responses, the propagation loss of the Airy SPPs can be largely suppressed when the optical frequency is close to the lossless point of the NIMM. As a result, the Airy SPPs obtained…

Photonic Hook Plasmons: A New Curved Surface Wave

Today the surface plasmon‐polariton (SPP) waves propagating along the curve trajectory are the only plasmonic beams of the Airy family. Herein, a new class of curved surface plasmon wave, the

Airy plasmon: a nondiffracting surface wave.

A new class of nondiffracting surface plasmonic wave is introduced: the Airy plAsmon, which has propagation properties that are unique among the family of surface waves and could lead to interesting applications in pl asmonic energy routing.

Airy plasmons: non‐diffracting optical surface waves

Airy beams represent an important class of non‐diffracting waves which can be realized on a flat surface. Being generated in the form of surface‐plasmon polaritons, such Airy plasmons demonstrate

Coherent control of low loss surface polaritons.

It is shown that an EIT medium near the interface between a dielectric and a negative-index metamaterial can establish tight longitudinal and transverse confinement plus extreme slowing of surface polaritons, in both transverse electric andTransverse magnetic polarizations, while simultaneously avoiding losses.

We propose a scheme to generate (3 +1)-dimensional slow-light Airy wave packets in a resonant � -type three-level atomic gas via electromagnetically induced transparency. We show that in the absence
