Energy flux of a vortex field focused using a secant gradient lens
Компьютерная оптика, 2020 In this paper we simulated the focusing of left circular polarized beam with a second order phase vortex and a second-order cylindrical vector beam by a gradient index Mikaelian lens.

Analysis of characteristics of paraxial vector Gaussian beams affecting the formation of microstructures in an azopolymer [PDF]
Компьютерная оптика, 2019 The paper considers paraxial Gaussian laser beams with different polarization states and their characteristics, such as the Poynting vector, gradient force, and force density, which are important for evaluating the effects of radiation on matter.

Giant Magnetic Purcell Effect Induced by High‐Order Mie Resonances
Advanced Science, EarlyView.High‐order Mie resonances in dielectric spheres selectively amplify magnetic dipole emission from Eu3+ emitters, producing a giant magnetic Purcell effect. Localized emitters can efficiently access high‐order resonant modes, and the low‐loss TiO2 platform enables direct far‐field observation of the enhanced emission.

The Non-Vortex Inverse Propagation of Energy in a Tightly Focused High-Order Cylindrical Vector Beam
IEEE Photonics Journal, 2019 In this paper, the tight focusing of high-order cylindrical vector beams (beams with polarization singularity) was investigated. Using the Richards–Wolf formalism, there were obtained expressions for all projections of the electric and magnetic ...

The Canadian Journal of Chemical Engineering, EarlyView.We clarify how Gibbs‐energy‐minimization models for aqueous‐amine CO2 capture fail when conservation constraints and concentration conventions are inconsistent. Exact standard‐state conversions and Reaktoro case studies show that P(CO2)‐loading fits can mask non‐unique parameters and wrong speciation, motivating complete water‐inclusive formulations ...

Diffraction‐Free Natural Optical Skyrmions and Their Subwavelength Confinement Around Vortices
Laser &Photonics Reviews, EarlyView.ABSTRACT Diffraction causes waves to spread out as they propagate freely. The tighter the lateral confinement, the faster the spreading. Past research on how to suppress diffraction has been based on wave engineering and has led so far to idealized waves that, in real settings, eventually diffract.

Laser &Photonics Reviews, EarlyView.A picopatch in a plasmonic nanocavity confines the electromagnetic energy to tiny effective volumes, close to 1nm3, leading to extreme electric field enhancements. Furthermore, a clear signature of strong coupling between the picopatch modes and other modes of the structure is obtained, which strongly modifies the far‐field response. ABSTRACT Plasmonic

Energy and momentum flux in a high-numerical-aperture beam using the extended Nijboer-Zernike diffraction formalism [PDF]
Journal of the European Optical Society-Rapid Publications, 2007 We describe the energy and momentum flux in the case of an aberrated optical imaging system with a high numerical aperture (NA). The approach is based on the extended Nijboer-Zernike diffraction theory, that, in its high-NA version, yields an accurate ...
