New method of disturbance by imposing harmonic signals on discharge current in DC glow discharge with ordered structures is studied at low values of disturbing amplitudes in molecular nitrogen. Influence of disturbing signals with frequencies from 10 Hz to 100 kHz is observed. New effects of changing vertical size and position of dusty structures in discharge space observed. Forced oscillations of dust particles and self‐oscillating crystals stabilizing effect under different conditions registered. Studied dusty structure's vertical size change dependencies on frequency and amplitude of disturbing signal (© 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
