Angular Momentum of Light with Plane Phase Front

Authors: Khrapko R. I.

We consider two different types of angular momentum of electromagnetic radiation. 1) Moment of linear momentum, which we consider as orbital angular momentum. 2) Spin, which is not a moment of momentum; its origin is a circular polarization. We show that a circularly polarized light beam with plane phase front carries angular momentum of both types, spin and orbital angular momentum, contrary to the standard electrodynamics. Because of the conservation laws of momentum and total angular momentum, spin and moment of momentum have concrete values. These two types of angular momentum are spatially separated. Flux of spin and flux of moment of momentum act on an absorber independently. An experiment is described, which can verify this supposition.
