Non-diffracting airy surface plasmons: Generation, manipulation, and interference

We review our activities on the generation and manipulation of Airy surface plasmons. We demonstrate the excitation of surface Airy plasmon polaritons using a specially designed diffraction pattern. We predict and observe the generation of a plasmonic hot-spot on the surface of metal by the interference of two Airy surface plasmons. We also show an Airy plasmon trajectory manipulation in a system with linear gradient of refractive index.
