Abstract
Official abstract text for this publication.
Systems according to the present disclosure provide one or more surfaces that function as heat or 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 (plasmonic) wave causes near replication of current present in one fractal cell in an adjacent fractal cell. A fractal of such a fractal cell can be of any suitable fractal shape and may have two or more iterations. 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.
First claim
Opening claim text (preview).
What is claimed is: 1. An electromagnetic radiative system providing gain over a prescribed bandwidth, the system comprising: a plurality of fractal-cell layers, each layer having a fractal plasmonic surface (FPS) including close-spaced fractal cells, wherein the plurality of fractal-cell layers is operative to produce a gain increase, and wherein the gain increase acts as a lens-like effect on a separate electromagnetic source; and wherein the fractal cells lie on a flat layer…
