Abstract

An improved field emission system and method is provided that involves field emission structures having electric or magnetic field sources. The magnitudes, polarities, and positions of the magnetic or electric field sources are configured to have desirable correlation properties, which may be in accordance with a code. The correlation properties correspond to a desired spatial force function where spatial forces between field emission structures correspond to relative alignment, separation distance, and the spatial force function.

a first field emission structure, said first field emission structure comprising a first plurality of field emission sources having positions and polarities in accordance with a spatial force function, said first plurality of field emission sources being arranged in a first circular ring; and
