Abstract

Three-dimensional plots of dispersion in a cold anisotropic plasma are presented. The ω(κ, θ) surfaces provide a clear picture of the behaviour of cold plasma waves as the direction of propagation is varied. The group velocity (dω/dκ) has a simple geometrical interpretation on the surfaces.
