Abstract

Diffracted waves are widespread in nature. They can be generated by the scattering with disordered and/or ordered system. Topological defects, such as phase dislocations or polarization singularities, can be hidden in complicated field pattern that arises from this multiple scattering [1]. These singularities are generic properties of waves and can be found in different field of research (tidal theory, optics, Bose-Einstein condensation, superconductivity, superfluidity, high energy physics, etc.).
