AB Transition radiation by a non-relativistic electron bunch that crosses an interface of a vacuum/left-handed material has been theoretically investigated. The electron density of the bunch is described by the Gauss distribution. It is shown that as a result of the transition radiation both bulk and surface electromagnetic waves can be excited in the frequency region where the refractive index of the left-handed medium is negative. At the same time the dispersion of the surface electromagnetic waves can be negative as well as positive, depending on the relation between the plasma frequency and the resonance frequency of a left-handed material. The energy flows of the surface and bulk electromagnetic waves have been calculated.
