Paper Abstract

A general study of transverse energy flows (TEF) as physically meaningful and informative characteristics of paraxial light beams' spatial structure is presented. The total TEF can be decomposed into the spin and orbital contributions giving rise to the spin and orbital angular momentums, correspondingly. Definitions and properties of these constituents are discussed in relation with the optical field representation through linear and circular orthogonal polarization bases. An analysis of TEFs near singular points has been carried out. General discussion of the evolution of the optical field singularities is presented. Possible mechanical action of light beams associated with the TEF is studied on the example of an absorptive medium described by the Drude-Lorentz model.
