Modeling the longitudinal intensity pattern of diffraction resistant beams in stratified media.

In this paper, we study the propagation of the frozen wave (FW)-type beams through non-absorbing stratified media and develop a theoretical method capable of providing the desired spatially shaped diffraction-resistant beam in the last material medium. In this context, we also develop a matrix method to deal with stratified media with a large number of layers. Additionally, we undertake some discussion about minimizing reflection of the incident FW beam on the first material interface by using thin films.
