Abstract
In this paper, we present a simple and effective method, based on appropriate superpositions of Bessel-Gauss beams, which in the Fresnel regime is able to describe in analytic form the 3D evolution of important waves as Bessel beams, plane waves, Gaussian beams, Bessel-Gauss beams, when truncated by finite apertures.
