Brief description, advantages, further prospects for application.

A unified and supplemented system of dynamic characteristics (DC) of monochromatic vector light fields has been developed as a means of characterizing their structure, morphology, and physical properties.

A theory is developed and the physical mechanisms of the spin and orbital optical Hall effect in the diffraction of structured beams are determined, which is based on taking into account the partial contributions of individual polarization components of the field and the features of the diffraction of the longitudinal component.

A theory has been developed for the formation and transformation of the topological structure and DC of a light field under conditions of diffraction of circular light beams with optical vortices by one-dimensional inhomogeneous interference. Recommendations are developed on the possible application of the obtained results for the diagnostics of fields and media, the generation of fields with desired properties, in the problems of nanoengineering, micromanipulation, and for encoding, transmitting and processing information.
