Airy–Talbot plasmon: an accelerating self-imaging surface wave

Not Accessible

Your library or personal account may give you access

Abstract

In this Letter, a new class of an accelerating self-imaging surface plasmonic wave, the Airy–Talbot plasmon, is introduced for the first time, to the best of our knowledge. Our research shows that such a surface wave propagates at the interface between metal (silver) and a dielectric material (air) and causes a strong interference along curved trajectories, which generates the Talbot effect in the surface. The propagation properties have potential value in nanoscale plasmonic devices. A scheme for generating this novel plasmon theoretically is proposed, and we prove it by finite difference time-domain numerical simulations.
