Abstract
A ring-shaped two-dimensional electron gas on the surface of liquid he lium is created by electrostatic confinement. The very low-frequency r esponse to a capacitively coupled driving field is investigated in str ong magnetic fields. It is found that an edge magnetoplasmon exists bo th at the outside edge and at the inside edge of the ring. The two mod es propagate in opposite directions.
