Abstract

Systems according to the present disclosure provide one or more surfaces that function as power radiating surfaces for which at least a portion of the radiating surface includes or is composed of “fractal cells” placed sufficiently closed close together to one another so that a surface wave causes near replication of current present in one fractal cell in an adjacent fractal cell. The fractal cells may lie on a flat or curved sheet or layer and be composed in layers for wide bandwidth or multibandwidth transmission. The area of a surface and its number of fractals determines the gain relative to a single fractal cell. The boundary edges of the surface may be terminated resistively so as to not degrade the cell performance at the edges. The fractal plasmonic surfaces can be utilized to facilitate electrical conduction with lower ohmic resistance than would otherwise be possible in the absence of the fractal plasmonic surface(s) at the same temperature.

First claim

What is claimed is:

1. A plasmonically-coupled resonator system, the system comprising:
a plurality of close-packed fractal cells disposed on a supporting surface, wherein each fractal cell includes a fractal shape defining an electrical resonator, and
wherein the fractal cells of the plurality of fractal cells are positioned sufficiently close to one another to support plasmonic transfer of energy between the fractal cells;
wherein, for a given temperature, the plasmonically-coupled resonator system supports lower ohmic resistance than a respective surface composed of a continuous conductor; and
wherein the plurality of fractal cells is configured as a fractal plasmonic surface (FPS), wherein the FPS is operative to transfer power from one location on the FPS to another desired location on the FPS.

2. The system of claim 1 , wherein the FPS is configured as a wire.

3. The system of claim 1 , wherein the FPS is configured as a waveguide.

4. The system of claim 1 , wherein the FPS is configured as a manifold.

5. The system of claim 1 , wherein the FPS is configured as a power-conveyance structure.

6. The system of claim 5 , wherein the power-conveyance structure is a super conducting structure.
