The origin of periodic electron spatial structures in gases subject to spatially uniform electric fields E0 has been recently analyzed through fluid equations  thereby providing greater physical understanding of the 'window' phenomenon in the Franck-Hertz experiment, and complementing the more accurate but purely numerical results provided by Boltzmann's equation . Similar physical insight can be obtained for a spatially varying electric field, which modulates electron properties substantially if the applied wavelength matches the natural, 'Franck-Hertz' wavelength, simultaneously producing large phase shifts ('non-local effects'). Such cases have been analysed extensively through solutions of the Boltzmann equation  but never by physically tenable, benchmarked fluid modeling as described in [1, 4].
