Metamaterial and dynamically reconfigurable hologram employing same

摘要

A negative index material (or metamaterial) crossbar includes a first layer of approximately parallel nanowires and a second layer of approximately parallel nanowires that overlay the nanowires in the first layer. The nanowires in the first layer are approximately perpendicular in orientation to the nanowires in the second layer. Each nanowire of the first layer and each nanowire of the second layer has substantially regularly spaced fingers. The crossbar further includes resonant elements at nanowire intersections between the respective layers. Each resonant element includes two fingers of a nanowire in the first layer and two fingers of a nanowire in the second layer.

1. A negative index material crossbar comprising:
a first layer of approximately parallel nanowires, each nanowire of the first layer having substantially regularly spaced fingers; a second layer of approximately parallel nanowires that overlay the nanowires in the first layer, each nanowire of the second layer having substantially regularly spaced fingers, wherein the nanowires in the first layer are approximately perpendicular in orientation to the nanowires in the second layer; and resonant elements at nanowire intersections, wherein each resonant element includes two fingers of a nanowire in the first layer and two fingers of a nanowire in the second layer, wherein a finger comprises a protuberance extending from a side of a nanowire, the fingers being separated by notches.
