Analysis of the orbital angular momentum of paraxial light beams shows that a key role in the formation of this quantity is played by phase relations between longitudinal and transverse radiation fields. When a light beam is circularly polarized or has a helical wave front, the azimuthal component...

and the wave vector of light, the refractive index of the material depends on the angle between the wave vector and the optical axis—nematic director field. Hence by rotating the nematic director field, optical properties of the material for a selected polarization (i.e. extraordinary beam) ar...
4i). Further analysis of the metalenses is given in Supplementary Note 8. Interestingly, the beam focus is asymmetric; that is the beam width remains relatively constant until the focal point, after which it starts to diverge significantly. This behavior, however, follows from the passive ...
-model fit of $ \pi^-\pi^-\pi^+$ states using the results of our previously published partial-wave analysis (PWA) of a large data set of diffractive-dissociation events from the reaction $\pi^- + p o \pi^-\pi^-\pi^+ + p_{recoil}$ with a 190 GeV/${\it c}$ pion beam....
(C) Pattern generation using three-beam illumination, one beam along the optical axis (wavevectork0) and two beams along marginal rays (wavevectorsk1andk2). (D) Fourier components of the illumination pattern corresponding to (C) (white dots) and Fourier components of the sample that become ...
Ho et al. [8] combined an artificial neural network and an ant lion optimizer to overcome the disadvantages of the beam failure identification method based on the mode shape. The proposed method detects and quantifies the damage in plate-like structures better than conventional neural network ...
