We define an axisymmetric beam [74] (Gouesbet, Applied Optics 35(9), 1543–1555, 1996) to be a beam for which the z-component \(S_{z}\) of the Poynting vector, in which z is the direction of propagation of the beam, does not depend on the azimuthal angle \(\varphi \), in suitably chosen coordinate systems.
