For this reason, electromagnetic lenses used in electron microscopes would have little effect on the ion beam. The Hitachi FB-2000A FIB uses electrostatic lenses that focus the beam of heavy Ga ions.
An electrostatic loudspeaker uses a thin plastic diaphragm residing between two perforated metal sheets (the grids or stator plates). The audio signal is applied to the grids out of phase.
