Abstract
An apparatus, system, and/or method are described to enable optically transparent reconfigurable integrated electrical components, such as antennas and RF circuits to be integrated into an optically transparent host platform, such as glass. In one embodiment, an Ag NW film may be configured as a transparent conductor for antennas and/or as interconnects for passive circuit components, such as capacitors or resistors. Ag NW may also be used as transmission lines and/or interconnect overlays for devices. A graphene film may also be configured as active channel material for making active RF devices, such as amplifiers and switches.
