We would also like to thank the referees for their helpful comments on the manuscript.The angular momentum of non-uniformly totally polarized beams is investigated using methods from the beam characterization approach. The relationship between the elements of the beam matrix for the two components of the field and the angular momentum is given. The unconventional distribution of the polarization across the beam profile could result in contributions to both the spin and orbital terms of the angular momentum. To illustrate this, a particular example with a vortex beam is considered.engjournal articlehttp://www.sciencedirect.com/science/article/pii/S0030401809001321http://www.sciencedirect.comopen access535Variant Subwavelength GratingsPartially Coherent BeamsSpiral Phase PlatesOptical VorticesLaser-BeamsVortex BeamLightTransformationParametersParticlesFísica (Física)Óptica (Física)22 Física2209.19 Óptica Física
