AbstractIt is shown that, in reality, a circularly polarized light beam without an azimuthal phase structure carries the double angular momentum in comparison with the prediction of the standard Maxwell electrodynamics. So, the electrodynamics is not complete. A spin tensor is introduced into the electrodynamics.
