Abstract

Longitudinal waves in microcavities emerging because of spatial dispersion are investigated. It is shown that longitudinal modes similar to whispering-gallery modes exist in microcavities of this kind. These longitudinal modes should exist in metal microcavities in the vicinity of the plasma frequency.
