Line 1: {{WikiProject banner shell\|class=Start\| {{~~physics\|class=start~~WikiProject Physics\|importance=mid}} }} == Paraxial approximation == The approximation done, by which the results are accurate only for directions close to k_0, is called paraxial approximation. The assumption that the higher order derivatives are considerably smaller that the first order derivative and can be therefore neglected is not a consequence of the SVEA, but it is the paraxial approximation itself. It is indeed an assumption that usually accompanies the SVEA, but it is not necessary. See for example: Hadley (1992), Wide-Angle beam propagation using Pade approximant operators, Optics Letters Vol 17 No 20.
