Abstract

An improved field emission system and method is provided that involves field emission structures having electric or magnetic field sources. The magnitudes, polarities, and positions of the magnetic or electric field sources are 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 relative alignment, separation distance, and the spatial force function.

Claims

1. A system for producing a magnetic field emission structure, comprising:

a magnetizer configured to generate a magnetic field, said magnetizer comprising a flat metal inductor coil having flat coils and a central hole whose width is smaller than the width of the flat coils;

a material handler configured to move in a coordinate system (X,Y,Z) a magnetizable material relative to the magnetizer to a number of appropriate locations;

a trigger configured to supply a current to said magnetizer where a selected location is reached to produce a magnetic field;

a high voltage DC source;

a charging switch;

a charging resistance;

one or more back diodes;

one or more energy storage capacitors;

a silicon-controlled rectifier; and

a pulse transformer;

wherein the polarity and magnitude of the magnetic field is controlled to create a plurality of magnetic field sources into said magnetizable material having polarities in accordance with elements of a code corresponding to a desired force function.

2. The system of claim 1, wherein said magnetizer further comprises a plurality of silicon-controlled rectifiers and a plurality of pulse transformers configured in bridge circuit.

3. The system of claim 1, wherein said magnetizer is a bipolar magnetizer.

4. The system of claim 1, wherein the field strengths of said plurality of magnetic field sources can be varied.

5. The system of claim 1, wherein said coil is coupled to a core.

6. The system of claim 5, wherein said core comprises one of Mu-metal, Permalloy, electrical steel, or Metglas Magnetic Alloy.
