Two different classes of vector beams that have the same paraxial approximation

It is observed that there exist two different classes of vector light beams that have the same first-order paraxial approximation. They are characterized by the axial and transverse orientations of a constant unit vector that comes from the constraint of transversality condition. Their vectorial str...

Description
Summary:It is observed that there exist two different classes of vector light beams that have the same first-order paraxial approximation. They are characterized by the axial and transverse orientations of a constant unit vector that comes from the constraint of transversality condition. Their vectorial structures in the nonparaxial regime and angular momentum properties are compared.
