Penetration of Accelerated Multivalent Ions through a System of Parallel Thin Films

Fields of polarization that appear during the penetration of multiply charged ions through ultrathin nanomembranes are calculated by means of classical electrodynamics. The ponderomotive forces generated by these fields are able to press pores out of membranes. The dimensions of the penetrating ions’ wave packets determine the sizes of these pores. Calculations describe the experimental data on penetration through one film and through a system of four parallel films.
