Focusing a second-order cylindrical vector beam with a gradient index Mikaelian lens [PDF]
Компьютерная оптика, 2020 In this paper, we numerically simulate the focusing of a second-order cylindrical vector beam with a gradient index Mikaelian lens. It is shown that the lens forms a region of the reverse energy flow near its output surface.

An orbital energy flow and a spin flow at the tight focus
Компьютерная оптика, 2021 We have shown that a reverse energy flow (negative projection of the Poynting vector onto the optical axis) at the sharp focus of an optical vortex with topological charge 2 and left-hand circular polarization arises because the axial spin flow has a ...

Effects of fabrication errors on the focusing performance of a sector metalens [PDF]
Компьютерная оптика, 2018 Using e-beam lithography, a 16-sector spiral metalens was fabricated in an amorphous silicon, capable of converting linearly polarized incident light into an azimuthally polarized optical vortex. When illuminated by a 633-nm linearly polarized laser beam,

A Simulation Study of Ultra-relativistic Jets. III. Particle Acceleration in FR-II Jets
The Astrophysical Journal, 2023 We study the acceleration of ultra-high-energy cosmic rays (UHECRs) in Class II Fanaroff–Riley (FR-II) radio galaxies by performing Monte Carlo simulations for the transport, scattering, and energy change of CR particles injected into time-evolving jet ...
