Abstract:
1. A stacked field emission system having an outer surface, comprising: at least three field emission structure layers having a stacked relationship that defines a field characteristic of the outer surface; a constraining mechanism for maintaining said at least three field emission structure layers in said stacked relationship by holding the at least three field emission structure layers such that a plurality of interface surfaces of the at least three field emission structure layers correspond to a plurality of interface boundaries between adjacent field emission structure layers; wherein each of said at least three field emission structure layers comprises a plurality of field emission sources having positions, polarities, and field strengths in accordance with a spatial force function that corresponds to a relative alignment of said at least three field emission structure layers in the stacked relationship; wherein each field emission source of said at least three field emission structure layers has one of a first vector direction or a second vector direction, said second vector direction being opposite said first vector direction, said first vector direction and said second vector direction corresponding to a magnetization angle relative to said plurality of interface boundaries; wherein vectors of field emission sources of at least two interfacing field emission structure layers can be aligned to produce at least one vector path that enables field emissions to travel through the at least two interfacing field emission structure layers; wherein vectors of field emission sources of at least two interfacing field emission structure layers can be misaligned resulting in vector cancellation; and wherein a movement of at least one of said at least three field emission structures varies the field characteristics of the outer surface.
