Abstract
Maximum decelerations and their resonance frequencies are obtained for plasmons in a thin metal layer. Anomalous negative dispersion and backward plasmons are considered. It is shown that negative dispersion in structures with dissipation does not always imply the presence of a backward plasmon.
