摘要：

The single-particle energy eigenvalues and eigenfunctions as well as the magnetoplasmon dispersion relation are calculated for a Landau quantized two-dimensional square array of antidots. Comparison is made with recent measurements of the magnetoplasmon excitation energies for antidots. Some unique features observed in the experiment of Kern et al. [Phys. Rev. Lett. 66, 1618 (1991)] have been reproduced in numerical calculations and explained theoretically.
