Measuring of Transverse Energy Flows in a Focus of an Aluminum Lens
Photonics, 2022 In this study, we theoretically and experimentally investigate the propagation of a second-order cylindrical vector beam through an aluminum lens which forms a tight focus at the distance of the wavelength. Simulation by the finite-difference time-domain

From Poynting vector to new degree of freedom of polarization
, 2020 Up till now, the Jones vector is, strictly speaking, only a notion about the state of polarization of plane electromagnetic waves though it is generally applied to paraxial fields approximately. Here we generalize it to non-paraxial fields.

A decomposition of light’s spin angular momentum density
Light: Science & ApplicationsLight carries intrinsic spin angular momentum (SAM) when the electric or magnetic field vector rotates over time. A familiar vector equation calculates the direction of light’s SAM density using the right-hand rule with reference to the electric and ...
