Abstract
AbstractIn this paper, we experimentally and numerically studied the wave‐like excitations in the system comprised by a charged nylon filament (macroobject) and charged microparticles levitating in a linear quadrupole electrodynamic trap. It has been found out that a filament with sufficient sag forms a rotating standing‐like wave, while the particles due to the Coulomb repulsion are localized in its antinodes. Numerical simulation shows that this dynamic collective motion can be excited at high enough voltages on the electrodes, when the energy losses due to air viscosity can be compensated by the energy contribution of the altering electric fields of the trap.
