The paper briefly presents some essential concepts and features of light fields with strong
spatial inhomogeneity of amplitude, phase, polarization, and other parameters. It contains a …

Polarization singularities are superpositions of orbital angular momentum (OAM) states in
orthogonal circular polarization basis. The intrinsic OAM of light beams arises due to the …

We describe experimental results exposing the possibilities of optical crystals, especially
anisotropic and birefringent, for creation, control, and diagnostics of structured light fields …

The momentum of light beams can possess azimuthal densities, circulating around the
beam axis and inducing intriguing mechanical effects in local light-matter interaction …

We generate tightly focused optical vector beams whose electric fields spin around an axis
transverse to the beams' propagation direction. We experimentally investigate these fields …

The Belinfante spin momentum (BSM) is a fundamental yet enigmatic quantity of
electromagnetic fields. It vanishes from the global momentum of the field, but can be …

We provide a vivid demonstration of the mechanical effect of transverse spin momentum in
an optical beam in free space. This component of the Poynting momentum was previously …

We investigate the spin angular momentum (SAM) of double-index cylindrical vector beams
in tight focus. Such a set of beams is a generalization of the conventional cylindrical vector …

Polarization singularities are superpositions of orbital angular momentum (OAM) states in
orthogonal circular polarization basis. The intrinsic OAM of light beams arises due to the …

The idea of the proposed paper is a demonstration of the evanescent wave effect on nano-
objects of inorganic and organic (in particular, formed blood elements) origin localized in a …
