Paper Abstract

Macroscopic continuity equation for the angular momentum (AM) of radiation, valid in arbitrary media, is built. The expression for sources of the AM are obtained. On the basis of the equation the stability of the total AM flux in round weakly guiding optical fibers with elliptically deformed section is investigated. The conservation of the total AM flux of the circular optical vortex in the first order in deformation is demonstrated. On the basis of the equation an approximate expression for the torque acting on an absorbing particle in arbitrary electromagnetic field is obtained. The comparison with the know results is carried out.
