Properties of vectorial paraxial light beams. I. Homogeneous polarization

The simple formalism for the description of the vector paraxial light beams of general type is offered. Simple expressions for the energy flux density of the electromagnetic field $\mathbf{S}$ of the vector light beams with the homogeneous polarization are discovered. It is discovered that paraxial circular polarized light beams are spread independently, and their streams of energy are parted and they are also independent.
