Patent ID: 8760252

Claim:
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 three or more field emission sources each having a field emission amplitude and a vector direction 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 having a length equal to the length of said code, said code defining only one peak spatial force and a plurality of off peak spatial forces per said code modulo, 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 plurality of off peak spatial forces comprising a plurality of resultant forces resulting from cancellation of at least one attract force produced by aligned field emission sources of said first and second field emission structures by at least one repel force produced by aligned field emission sources of said first and second field emission structures, each resultant force of said plurality of resultant forces being one of an attract force or a repel force, wherein each field emission source of said first field emission structure and of said second field emission structure have a first vector direction or a second vector direction that is opposite said first vector direction.
