Canonical and Poynting currents in propagation and diffraction of structured light: tutorial
Bohnishikha Ghosh, Anat Daniel, Bernard Gorzkowski +3
Local propagation and energy flux in structured optical fields is often associated with the Poynting vector. However, the local phase gradient (i.e., local wavevector) in monochrom…
Energy and momentum of the surface plasmon-polariton supported by a thin metal film
A. Y. Bekshaev, O. A. Angelsky
We study the energy and momentum of the surface plasmon-polariton (SPP) excited in a symmetric 3-layer "insulator-metal-insulator" structure, which is known to support the symmetri…
Microscopic analysis of the energy, momentum and spin distributions in a surface plasmon-polariton wave
Aleksandr Bekshaev, Oleg Angelsky, Jun Zheng +2
We analyze the electromagnetic field near a plane interface between a conductive and a dielectric media, under conditions supporting surface plasmon-polariton (SPP) propagation. Th…
Optical-vortex diagnostics via Fraunhofer slit diffraction with controllable wavefront curvature
A. Bekshaev, L. Mikhaylovskaya, S. Patil +2
Far-field slit-diffraction of circular optical-vortex (OV) beams is efficient for measurement of the topological charge (TC) magnitude but does not reveal its sign. We show that th…
Transformation of the singular skeleton in optical-vortex beams diffracted by a rectilinear phase step
Aleksandr Bekshaev, Anna Khoroshun, Lidiya Mikhaylovskaya
Based on the Kirchhoff-Fresnel approximation, we numerically analyze spatial characteristics of the light field formed after a circular Laguerre-Gaussian beam with a single-charged…
Spectral characteristics of the Fabry-Perot interferometer transmission upon illumination by an arbitrary light beam
A. Ya. Bekshaev, V. M. Grimblatov, O. N. Okunisnikov +2
It is known that spectral properties of the Fabry - Perot interferometer (FPI) depend on the spatial characteristics of the incident radiation. This paper proposes a general method…
