Circular Polarization near the Tight Focus of Linearly Polarized Light
Photonics, 2022 We have considered the tight focusing of light with linear polarization. Using the Richards–Wolf formalism, it is shown that before and after the focal plane, there are regions in which the polarization is circular (elliptical).

Optical Polarization Sensor Based on a Metalens
Sensors, 2022 We investigated an optical microsensor of the polarization state of a laser light based on a metalens. In contrast to known polarization sensors based on metasurfaces that deflect different polarization types using various angles to the optical axis, the

Magnetically induced circular polarization
Physical Review A, 1987 Helium atoms excited to an aligned (1s3d)/sup 3/D state are produced by electron impact parallel to a magnetic field. The initial alignment of the atomic state evolves into an orientation with finite angular momentum along the magnetic field direction and thus gives rise to a circularly polarized component in the (1s3d)/sup 3/D..-->..(1s2p)/sup 3/P ...
