Abstract :
Summary form only given. In a laboratory experiment, dust density waves are observed in a 3D void-free dusty plasma. Dust particles are levitated within the volume of a glass box that rests atop an electrode in a radio-frequency glow-discharge plasma. Confinement of dust particles is provided by an electric force. The vertical electric field is due to the electrode´s sheath, while the lateral electric field is due to the walls of the glass box.
