1. A field emission system, comprising:

  • a first field emission structure; and

    a second field emission structure, said first and second field emission structures each comprising an array of field emission sources each having positions and polarities relating to a spatial force function that corresponds to the relative alignment of the first and second field emission structures within a field domain, said spatial force function being in accordance with 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 code defining a 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 also 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.
