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.

producing a first field emission structure, said first field emission structure including a first plurality of field emission sources having positions, polarities, and field strengths in accordance with a spatial force function having a peak spatial force having a force direction, said first field emission being able to rotate about an axis that is substantially parallel to said spatial force direction;

producing a second field emission structure, said second field emission structure including a second plurality of field emission sources having positions, polarities, and field strengths in accordance with said spatial force function, said second field emission being unable to rotate about said axis; and

rotating said first field emission structure about said axis at a desired revolution rate at a distance from said second field emission structure where said peak spatial force is produced and repeats at said revolution rate, said spatial force function being defined by a code, said code corresponding to a code modulo of said first field emission structure and a code modulo of said second field emission structure, said peak spatial force corresponding to substantial alignment of said code modulo of said first field emission structure with said code modulo of said second field emission structure, said code defining a plurality of off peak spatial forces corresponding to a plurality of different misalignments of said code modulo of said first field emission structure and said code modulo of said second field emission structure, 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.
