ABSTRACT:
Several embodiments of a thin film field emission cathode array are described which automatically shape the beams of emitted particles, without the addition of shaping or other electrode structure. A potential field pattern is established to control the trajectory of the emitted particles, by controlling the electromagnetic interaction of the conductive structures responsible for the particle emission.
