• G. Gbur (UK) — “Deterministic singularities in partially coherent vortex beams”,

• J.-Yo. Son (Korea), T. Venkel (Ukraine)— “Color Moires for security applications”,

• K.Y. Bliokh (Spain) — “Topologically structured waves and manipulation of particles”,

• Y. Miyamoto (Japan) — “Scattering and change in non-separability of light”,

• M. Dennis (UK) — “Skyrmionic textures in optical polarization patterns: Stokes origami”,

• W. Wang (UK), M. Takeda (Japan) — “Vector Direct Correlation of Electric Fields and Its Application to Unification of Coherence and Polarization of Light”,

• L. Marrucci (Italy) — “Photonic quantum circuits in free space with structured light”,

• A. Dogariu (USA) — “Optical Sensing with Structured Wavefronts”.

The poster session featured two subsections on the topics “New applications of correlation optics in biology and medicine” and “Digital, information and communication transformation of scientific and educational processes in the context of global changes”, with a total of 38 poster presentations. Participants actively discussed the results and engaged in lively debates during the session.
