Topological Charge of Light Fields with a Polarization Singularity
Photonics, 2022 We have studied diverse vector and hybrid light fields, including those with multiple polarization singularities, and have derived relationships for polarization singularity indices based on the familiar Berry formula, which is normally utilized to find ...

Fresnel and Fraunhofer diffraction of a Gaussian beam with several polarization singularities [PDF]
Компьютерная оптика, 2018 Alongside phase singularities (optical vortices), there may be light fields with polarization singularities (PS), i.e. isolated intensity nulls with radial, azimuthal, or radial-azimuthal polarization around them.

Spin angular momentum of Gaussian beams with several polarization singularities
Компьютерная оптика, 2023 We study a paraxial vector Gaussian beam with several polarization singularities located on a circle. Such a beam is superposition of a cylindrically polarized Laguerre-Gaussian beam and a linearly polarized Gaussian beam.

Polarization singularities of focused, radially polarized fields [PDF]
Frontiers in Optics, 2006 The state of polarization of strongly focused, radially polarized electromagnetic fields is examined. It is found that several types of polarization singularities exist. Their relationship is investigated, and it is demonstrated that on smoothly varying a system parameter, such as the aperture angle of the lens, different polarization singularities can

Analysis on the Radial Vibration of Longitudinally Polarized Radial Composite Tubular Transducer [PDF]
Sensors, 2020 The radial vibration of a radial composite tubular transducer with a large radiation range and power capacity is studied. The transducer is composed of a longitudinally polarized piezoelectric ceramic tube and a coaxial outer metal tube. Assuming that the longitudinal length is much larger than the radius, the electromechanical equivalent circuits of ...
