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 …

Geometric phases are a universal concept that underpins numerous phenomena involving
multi-component wave fields. These polarization-dependent phases are inherent in …

A spherical nanoparticle can scatter tightly focused optical beams in a spin-segmented
manner, meaning that the far field of the scattered light exhibits laterally separated left-and …

Polarization singularities in momentum space, including bound states in the continuum
(BICs) and circularly polarized states (CPSs), render great potential in singular and chiral …

Tiny but universal beam shifts occur when a polarized light beam is reflected upon a planar
interface. Although the beam shifts of Gaussian beams have been measured by the weak …

Structured illumination allows for satisfying the first Kerker condition of in-phase
perpendicular electric and magnetic dipole moments in any isotropic scatterer that supports …

The topic of optical precise displacement measurement has garnered significant attention
and generated widespread interest recently. The use of optical singularity offers a potential …

We experimentally demonstrate the emergence of an azimuthally polarized vectorial vortex
beam with a phase singularity upon Brewster reflection of focused circularly polarized light …

In this paper, a momentum-space geometrical structure in helical evanescent
electromagnetic waves is revealed. It is shown that for every helical evanescent wave on a …
