Mechnikov National University popup.description1 Development and substantiation of new concepts and approaches to the formation and management of properties of structured light fields for purposeful interaction between the field and an inhomogeneous medium. Development of the principles of investigation, optical diagnostics and control of functional media and principles of application of developed concepts in critical information technologies and in the dual-use systems. popup.description2  A unified system of dynamic characteristics (DC) for monochromatic light fields has been developed as a means of characterizing their structure, morphology, and physical properties. Within the framework of the consistent theory of DC for paraxial light fields, the concept of extraordinary spin has been introduced as a consequence of "hidden" vorticity of inhomogeneous longitudinal energy flow, and the origin of the transverse extraordinary momentum (EM) has been clarified as a manifestation of the inhomogeneity of the beam’s elliptical polarization. It is shown that in arbitrary inhomogeneous media, EM can be described as the spin part of the spin-orbit decomposition of the Minkowski electromagnetic momentum with dispersion-modified expressions for the permeabilities. A theory is developed of the spin accumulation and static magnetic field generation in nonmagnetic conducting media under the action of electromagnetic surface waves. A comparative study of the spectral sensitization of photosensitive heterophase “core-shell” nano- and microsystems (CS-HNMS) has been performed using the example of a J-aggregating anionic dye, and a mathematical model of CS-HNMS luminescence has been created, which accounts for the existence of two deep electron traps and two direct recombination channels. A high-speed single-frame method of phase-modulated speckle interferometry of optically dense media containing a condensed phase was developed. The effect of silver nanoparticles and UV irradiation on the phagocytic activity of human blood neutrophils is studied, and their anti-tumor effect has been established. The results will contribute to development of a system of physical parameters for the description and characterization of light fields in spatially and spectrally inhomogeneous media, creation of new methods of forming light fields of desired structure, optical diagnostics, data encoding, processing and transmission, micromanipulation techniques, micro- and nanoengineering.
