Abstract

Disclosed are systems and methods for manufacturing energy relays for energy directing systems inducing Ordered Energy Localization effects. Ordered Energy Localization relay material distribution criteria are disclosed. Transverse planar as well as multi-dimensional ordered material configurations are discussed. Methods and systems are disclosed for forming non-random patterns of energy relay materials with energy localization properties.

Claims (19)

1. An energy relay, the energy relay comprising:

a plurality of first and second component engineered structures, each comprising a cross-sectional shape of a set of one or more shapes along a transverse plane of the energy relay;

wherein the plurality of first and second component engineered structures are arranged in a tiling across the transverse plane of the energy relay;

wherein the energy relay has higher energy transport efficiency along a longitudinal plane than along the transverse plane.

2. The energy relay of claim 1 , wherein at least one shape of the set of one or more shapes comprises a polygonal shape.

3. The energy relay of claim 1 , wherein the plurality of first and second component engineered structures are configured to cooperate to transport energy along the longitudinal plane of the energy relay.

4. The energy relay of claim 3 , wherein both the first and second component engineered structures are configured to transport at least 10% of the energy transported along the longitudinal plane.

5. The energy relay of claim 3 , wherein both the first and second component engineered structures are configured to transport energy through means other than internal reflection.

6. The energy relay of claim 3 , wherein the energy relay includes a first surface and a second surface, and wherein energy propagating between the first surface and the second surface travels along a path that is parallel to the longitudinal plane.

7. The energy relay of claim 1 , wherein the energy relay comprises a transverse distortion of the tiling.

8. An energy relay comprising:

a plurality of volumetric structures configured to tessellate volumetrically, each comprising one or more component engineered structures;

wherein the plurality of volumetric structures are located in an assembly according to a three-dimensional tessellation of the volumetric structures, the assembly being configured to transport energy in a longitudinal direction therethrough and having higher transport efficiency in the longitudinal direction than in a transverse direction, normal to the longitudinal direction;

wherein the three-dimensional tessellation of the volumetric structures is configured such that there is at least one substantially linear path through the volumetric tessellation, the substantially linear path coinciding with only similar component engineered structures, and oriented substantially parallel to the longitudinal direction.

9. The energy relay of claim 8 , wherein each of the plurality of volumetric structure comprises a plurality of substructures, each substructure comprising one of a first, second, or third component engineered structure.

10. The energy relay of claim 9 , wherein each of the first, second, or third component engineered structures comprises at least one of the following: any atomic or subatomic particles, glass, carbon, optical fiber, optical film, polymer or mixtures thereof.

11. The energy relay of claim 9 , wherein each substructure of the plurality of substructures comprises a square pyramidal shape, and is configured to assemble into the rhombic dodecahedral shape.

12. The energy relay of claim 8 , wherein the linear path coincides with only one of the first, second, or third component engineered structures.

13. The energy relay of claim 8 , wherein the energy relay includes a first surface and a second surface, and wherein energy propagating between the first surface and the second surface travels along a path that is parallel to the longitudinal direction.
