In this paper, we study the propagation of the Frozen Wave type beams throughnon-absorbing stratified media and develop a theoretical method capable toprovide the desired spatially shaped diffraction resistant beam in the lastmaterial medium. In this context, we also develop a matrix method to deal withstratified media with large number of layers. Additionally, we undertake somediscussion about minimizing reflection of the incident FW beam on the firstmaterial interface by using thin films. Our results show that it is indeedpossible to obtain the control, on demand, of the longitudinal intensitypattern of a diffraction resistant beam even after it undergoes multiplereflections and transmissions at the layer interfaces. Remote sensing, medicaland military applications, noninvasive optical measurements, etc., are somefields that can be benefited by the method here proposed.
