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…

TLDR
Two recently reported solutions are members of a family of localized Bessel-Gauss beam solutions that can describe the entire transverse electric field in the paraxial limit.

Representation theory for vector electromagnetic beams

A representation theory of finite electromagnetic beams in free space is formulated by factorizing the field vector of the plane-wave component into a 3x2 mapping matrix and a two-component

Spin and orbital angular momentum of a class of nonparaxial light beams having a globally defined polarization

It is shown that the momentum density of free electromagnetic field splits into two parts. One has no contribution to the net momentum due to the transversality condition. The other yields all the

An overview of the recent developments in the field of cylindrical vector beams is provided. As one class of spatially variant polarization, cylindrical vector beams are the axially symmetric beam

A SCALAR REPRESENTATION OF ELECTROMAGNETIC FIELDS

It is shown that the scalar representation of electromagnetic fields introduced in an earlier paper leads to a new model for energy transport. The energy may be considered to be carried by two

Entangled vector vortex beams

Light beams having a vectorial field structure, or polarization, that varies over the transverse profile and a central optical singularity are called vector vortex (VV) beams and may exhibit specific

Measuring the nonseparability of vector vortex beams

Vector beams have the defining property of nonseparable spatial and polarization degrees of freedom and are now routinely generated in the laboratory and used in a myriad of applications. Here we

Free-space azimuthal paraxial wave equation: the azimuthal Bessel-Gauss beam solution.

TLDR
A paraxial wave equation for an azimuthally polarized field propagating in free space is developed and the propagation characteristics of the azIMuthal Bessel-Gauss beam solution are compared with a solution of the more familiar scalar paraxIAL wave equation, the linearly polarized Bessel - Gauss beam.

Commutation rules and eigenvalues of spin and orbital angular momentum of radiation fields

We investigate the separation of the total angular momentum J of the electromagnetic field into a 'spin' part S and an 'orbital' part L . We show that both `spin' and 'orbital' angular momentum are
