High-intensity wave vortices in the beamoptics domain: 3D spatial structure, singleplane models, and their propagation properties
I. Mokhun, O. Angelsky, A. Bekshaev +2
Typically, vortices in wave fields are associated with amplitude zeros. In contrast, recently described high-intensity (Type II) wave vortices appear near amplitude poles and can e…

Wigner function and intensity moments of spatio-temporal light fields
Aleksandr Bekshaev, Oleg Angelsky, Claudia Zenkova
The Wigner distribution function and its spatial-angular moments (intensity-moments) are known as efficient instruments for characterization of complex quasimonochromatic light bea…

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…
