In Edward Collet's book "Polarized Light: Fundamentals and Applications", Chapter 3 states that:
However, in recent years (as recent as 2008), I came across a paper published in Nature Photonics that a group of scientists, Haifeng Wang et al. from Data Storage Institute based in Singapore managed to generate a needle of longitudinally polarized light in free space with the help of binary optics and also radially polarized light. (nature photonics | VOL 2 | AUGUST 2008, Published online: 22 June 2008; doi:10.1038/nphoton.2008.127 pp. 501-505)
The conclusion of the paper states that:
My question is, does the creation of this longitudinal component actually violated Maxwell's Electrodynamic Theory? Is this phenomenon allowed in the Quantum theory?
Thanks for the help on insight on this matter.
One of the immediate results of solving his equations was that in free space only transverse components arose; there was no longitudinal component.

The conclusion of the paper states that:
In conclusion, we have proposed the generation of a
longitudinally polarized beam by focusing a radially polarized
beam using a binary optical element and a lens. This binary
optical element works like a special polarization filter, which
diffracts the radial field away from the centre of the beam more
than the longitudinal field, thus making the beam in the focal
region substantially longitudinally polarized. This beam
propagates without divergence for over 4l (a non-diffracting
beam). It is also highly localized in the transverse direction with
FWHM ¼ 0.43l (subdiffraction beam). The suggested method
achieves the required combination of conversion efficiency,
uniformity and field localization.
My question is, does the creation of this longitudinal component actually violated Maxwell's Electrodynamic Theory? Is this phenomenon allowed in the Quantum theory?
