If the value of ζ is not fixed, we can integrate over ζ ∈ [0,π] and, therefore, all free space solutions of the scalar wave equation can be decomposed into nondiffracting waves with different ζ's, i.e., with different velocities

Actually, a "sink" or a "source" cannot be defined mathematically, we must merely exclude the z axis from the space

The angular spectrum representation of nondiffracting waves may also be extended to include evanescent Bessel waves and their spectral generalizations. These waves are not, however, nondiffracting since their field amplitudes decay exponentially under propagation [53]
