Abstract:
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 different spatial forces produced by different spatial alignments of the first and second field emission structures within a field domain, said spatial force function being in accordance with a code modulo of a code, said code modulo having a length equal to the length of said code, said code defining only one peak spatial force per code modulo, each peak spatial force corresponding to a first spatial alignment of a plurality of the field emission sources of said first field emission structure and a plurality of the field emission sources of said second field emission structure, said peak spatial force being a spatial force produced when all aligned field emission sources produce an attractive force or all aligned field emission sources produce a repellant force, said code also defining a plurality of off peak spatial forces per code modulo, said plurality of off peak spatial forces corresponding to a plurality of second spatial alignments of said first and second field emission structures, each off peak spatial force of said plurality of off peak spatial forces resulting from cancellation of at least one attractive force produced by aligned field emission sources of said first and second field emission structures by at least one repellant force produced by aligned field emission sources of said first and second field emission structures.
