Field Emission System

Abstract

A magnetic system is provided that involves field emission structures having magnetic field sources, magnetically active intermediate layers, and magnetically inactive intermediate layers. The magnitudes, polarities, and positions of the magnetic field sources may be configured to have desirable correlation properties, which may be in accordance with a code. The correlation properties correspond to a desired spatial force function where spatial forces between field emission structures correspond to their relative alignment and separation distance.
