The structure of focused, radially polarized fields
Optics Express, 2006 We present a detailed analysis of the structure of strongly focused, radially polarized electromagnetic fields. The existence of phase singularities of the two components of the electric field is demonstrated. Two different mechanisms to obtain creation or annihilation of these phase singularities are discussed. These are changing the aperture angle of

A minimal subwavelength focal spot for the energy flux
Компьютерная оптика, 2021 It is shown theoretically and numerically that circularly and linearly polarized incident beams produce at the tight focus identical circularly symmetric distributions of an on-axis energy flux.

Flexoelectric radial polarization of single-walled nanotubes from first-principles
, 2022 Flexoelectricity is the polar response of an insulator to strain gradients such as bending. While the size dependence of this effect makes it weak in bulk systems in comparison to piezoelectricity, it suggests that it plays a bigger role in nanoscale ...

Fully symmetric diffraction-interference beam shaper for radially polarized light on a 1530-nm wavelength [PDF]
Компьютерная оптика, 2019 A completely symmetrical scheme of a shaper of cylindrical vector beams is proposed in which two diffractive axicons and an interference polarizer placed in-between form a sandwich structure of the smallest possible thickness. The design and experimental
