Abstract:
1. A coding method for a field emission system, comprising the steps of: specifying at least one characteristic of each of a plurality of first field emission sources of a first field emission structure in accordance with a first code; and specifying at least one characteristic of each of a plurality of second field emission sources of a second field emission structure in accordance with a second code, said first code and said second code defining a spatial force function, said first code corresponding to a code modulo of said plurality of first field emission sources, said second code corresponding to a code modulo of said plurality of second 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 plurality of first field emission sources with said code modulo of said plurality of second 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 plurality of first field emission sources and said code modulo of said plurality of second 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.
