Abstract:
1. An electronically programmable and erasable negative index material crossbar comprising: a first layer of approximately parallel nanowires, each nanowire having substantially regularly spaced fingers; a second layer of approximately parallel nanowires that overlay the nanowires in the first layer, each nanowire having substantially regularly spaced fingers, wherein the nanowires in the first layer are approximately perpendicular in orientation to the nanowires in the second layer, the substantially regularly spaced fingers of a respective nanowire in the first layer being approximately parallel to corresponding ones of the nanowires in the second layer; and resonant elements at nanowire intersections, each resonant element including two fingers of a nanowire in the first layer, two fingers of a nanowire in the second layer, and an intermediate layer sandwiched between the nanowire in the first layer and the nanowire in the second layer, wherein a refractive index of a first one of the resonant elements is to be controlled by a change in charge density within the intermediate layer.
