The evanescent wavefield part of a cylindrical vector beam. [PDF]

open access: yesOpt Express, 2013
The evanescent wave of the cylindrical vector field is analyzed using the vector angular spectrum of the electromagnetic beam. Comparison between the contributions of the TE and TM terms of both the propagating and the evanescent waves associated with the cylindrical vector field in free space is demonstrated.

Singularities in cylindrical vector beams [PDF]

open access: yesJournal of Modern Optics, 2015
Cylindrical vector beams with azimuthal and radial polarization distributions are studied for singularities. It is shown experimentally that these beams have screw dislocation as well as edge dislocation at the same time. The relation between phase and polarization of light beam is the key to understand this fact.
