    "abstract": "It is shown how the standard forms for the spin and orbital components of the\nangular momentum of a paraxial wave of electromagnetic radiation are obtained\nfrom the general expressions for the angular momentum that have been derived\nrecently. This result will enable the general expressions for angular momentum\nto be applied with confidence to the many configurations of electromagnetic\nfields that are more complicated than plane or paraxial waves.",
