Abstract

The characterization of static and dynamics of surface vorticity by surface waves interacting with filamentary vortex was investigated. Dislocations in the wave front and presence of a scattered wave were revealed by a visualization of a surface plane wave interacting with a single vortex. It was observed that the advection of the wave due to vortex circulation produces a phase shift responsible for dislocations and the vortex core in turn is responsible for the scattered wave. The results show that the Burgers vector in the regime accessible to the experiment is consistent with the simple analysis and the quantum mechanics analog introduced by Berry.
