Nanoelectronic crossbar arrays enable randomly addressable metamaterials with multispectral optical resonances

Crossbar nanoelectronic architectures, which are at the heart of today’s memristive and phase change random access memory technology such as ReRAM and PCRAM, presents a unique structural platform not only for providing ultrahigh device packing and simple interconnect configuration in electronic systems, but also for the realization of reconfigurable and randomly addressable metamaterials. We show here that these periodically arranged threelayered structures can be designed to display multiple Fano-type optical resonances spanning the visible to near-infrared $(400 \leq \lambda \leq 1700 nm)$ range of wavelengths.
