    摘要： A memristive routing device (200) includes a memristive matrix (240), mobile dopants (255) moving with the memristive matrix (240) in response to programming electrical fields and remaining stable within the memristive matrix (240) in the absence of the programming electrical fields; and at least three electrodes (210, 220, 230) surrounding the memristive matrix (240). A method for tuning electrical circuits with a memristive device (900) includes measuring a circuit characteristic (805) and applying a programming voltage to the memristive device (900) which causes motion of dopants within the memristive device (900) to alter the circuit characteristic (805). A method for increasing a switching speed of a memristive device (1300) includes drawing dopants from two geometrically separated locations into close proximity to form two conductive regions (1380, 1390) and then switching the memristive device (1300) to a conductive state by applying a programming voltage which rapidly merges the two conductive regions (1380, 1390) to form a conductive pathway between a source electrode (1310) and a drain electrode (1320).

    摘要： Transmitting nodes broadcast chirped signals on a wireless network. The transmitting nodes are time-synchronized with each other and location of the transmitting nodes is known. A receiver node detects beat frequencies created by pairs of chirped signals from different pairs of transmitting nodes. Time delay differences between chirped signals in respective beat frequency pairs are determined. The receiver node's location is determined in view of the time delay differences.

    摘要： A metamaterial inclusion structure (MIS), a metamaterial and a method of producing an optical magnetic response employ interspersed plasmonic and dielectric materials. The MIS includes first petals of a plasmonic material and second petals of a dielectric material that alternate at a surface and along a periphery of the MIS. The MIS exhibits the magnetic resonance when illuminated by an optical signal at an optical wavelength. The optical signal has a magnetic field component that is parallel with an interface between the first petals and the second petals. The metamaterial includes a plurality of the MIS arranged in an array and provides an optical magnetic susceptibility at the optical wavelength. The method forms the MIS with the alternating petals and includes illuminating the MIS with the optical signal.
