A simple method based on paraxial optics is presented which facilitates diffraction propagation cal-culations in all types of optical systems which have modest amounts of aberration, i.e. near-stigmatic systems. It is not only possible to apply the beam propagation method accurately to stigmatic GRIN media but a propagation distance of any length may be taken without using the split-step method. Studies of GRIN components have largely been either strictly geometrical in nature [2] or based on the split-step procedure. A recent publication has argued that the beam propagation method using split-step techniques has fundamental flaws in treating strongly inhomogeneous media such as Maxwell's fisheye lens [3]. The ABCD methods as popularized by Siegman [1 ! and others to treat paraxial optics, gaussian beams and diffraction propagation form the basis the generalized ABCD method.
