- Аннотация: The momentum and the density of the spin angular momentum of the electromagnetic field are found for a two-dimensional and three-dimensional elliptically polarized Airy beam in the first approximation in the angle of divergence. The choice of the beam is associated with its diffraction-free propagation in a homogeneous linear medium in the paraxial approximation. Due to this, diffraction effects appear only as corrections of the first order of smallness. For alinearly polarized beam, the appearance of the spin angular momentum is solely due to diffraction and is absent in the main order solution.
