摘要：

A ring-shaped two-dimensional electron gas on the surface of liquid helium is created by electrostatic confinement. The very low-frequency response to a capacitively coupled driving field is investigated in strong magnetic fields. It is found that an edge magnetoplasmon exists both at the outside edge and at the inside edge of the ring. The two modes propagate in opposite directions.
