An improved field emission system and method. The invention pertains to field emission structures comprising electric or magnetic field sources having magnitudes, polarities, and positions corresponding to a desired spatial force function where a spatial force is created based upon the relative alignment of the field emission structures and the spatial force function. The invention herein is sometimes referred to as correlated magnetism, correlated field emissions, correlated magnets, coded magnetism, or coded field emissions. The magnetic field sources may be arranged according to a code having a desired autocorrelation function. In particular, a high peak to sidelobe autocorrelation performance may be found desirable. Specific exemplary embodiments are described with magnetic field sources arranged in a ring structure. Exemplary codes are described and applied to magnetic field source arrangements. Specific codes found by the inventors are described.
