1. A field emission structure, comprising:
- a first plurality of field emission sources arranged in a first circular ring; and
a second plurality of field emission sources arranged in second circular ring, said first circular ring and said second circular ring being concentric, said first plurality of field emission sources and said second plurality of field emission sources having polarities and positions in accordance with a desired spatial force function, wherein positive and negative field emissions of said first plurality of field emission sources and said second plurality of field emission sources are substantially laterally balanced, said spatial force function being defined by a code, said code corresponding to a code modulo of said first plurality of field emission sources and a code modulo of said second plurality of field emission sources, said first code and said second code defining a peak spatial force corresponding to substantial alignment of said code modulo of said first plurality of field emission sources with said code modulo of said second plurality of field emission sources, said first code and said second code also defining a plurality of off peak spatial forces corresponding to a plurality of different misalignments of said code modulo of said first plurality of field emission sources and said code modulo of said second plurality of field emission sources, said plurality of off peak spatial forces having a largest off peak spatial force, said largest off peak spatial force being less than half of said peak spatial force.

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.
