A Low Complexity 2D Pattern Synthesis Algorithm for Cylindrical Array

open access: yesInternational Journal of Antennas and Propagation, 2013
This paper proposes a 2D pattern synthesis algorithm for cylindrical array. According to the geometric characteristic of cylinder, we can regard a cylindrical array as an equivalent linear array whose elements are identical circular subarrays. Therefore,

Spin Hall Effect before and after the Focus of a High-Order Cylindrical Vector Beam

open access: yesApplied Sciences, 2022
It is known that in the cross-section of a high-order cylindrical vector beam (CVB), polarization is locally linear. The higher the beam order, the higher the number of full rotations of the vector of local linear polarization when passing along a ...

Efficient optical trapping with cylindrical vector beams

open access: yesOptics Express, 2019
Radially and azimuthally polarized beams can create needle-like electric and magnetic fields under tight focusing conditions, respectively, and thus have been highly recommended for optical manipulation. There have been reports on the superiority of these beams over the conventional Gaussian beam for providing a larger optical force in single beam ...
