# New mechanism for polarization singularity of vector vortex beams

@article{Li2020NewMF, title={New mechanism for polarization singularity of vector vortex beams}, author={Chun-Fang Li}, journal={arXiv: Optics}, year={2020} }

It was recently realized that the polarization bases of the plane-wave modes in the integral representation of a light beam need to be determined by a degree of freedom arising from the divergence-free Maxwell's equation. This is a frequently introduced real unit vector in the literature, called Stratton vector. The polarization bases so determined are singular at the momentum that is parallel to the Stratton vector. Here we show that the polarization singularity of vector vortex beams given by…
