Abstract
A hydrodynamic model is used to study the magnetoplasma modes of a two-dimensional electron fluid confined to a thin circular disk and screened by two parallel grounded planes. For arbitrary values of the screening parameter, the equations are reduced to a single integral equation that is solved by expanding in a complete set of polynomials. The smallest resulting eigenfrequency for each angular quantum number represents the corresponding edge mode for this geometry.Keywords
