The electromagnetic fields generated by a superluminal electron in longitudinally magnetized, microwave ferrite have been derived for a narrow band of frequencies in the X band. For a superluminal electron, Cerenkov radiation is emitted in two circular cones for the ordinary and extraordinary wave modes. Using a Huygens' construction of wavelets, conditions for Cerenkov radiation were related to the propagation of plane waves through the ferrite. It was found that a slow relativistic electron will radiate only in the extraordinary wave mode. It is too slow to generate radiation in the ordinary wave mode.
