Rotating surface solitons

Abstract

We introduce a novel type of surface waves that form at the edge of guiding structures consisting of several concentric rings. Such surface waves rotate steadily upon propagation and, in contrast to nonrotating waves, for high rotation frequencies they do not exhibit power thresholds for their existence. There exists an upper limit for the surface wave ro-tation frequency, which depends on the radius of the outer guiding ring and on its depth.
