    摘要: An apparatus and related methods for modulating an electromagnetic radiation beam are described. A composite material is positioned in the path of the radiation beam, the composite material comprising a plurality of commonly oriented metallic first lines spaced apart by less than a wavelength of the radiation beam and a plurality of commonly oriented metallic second lines also spaced apart by less than that wavelength. The second lines are positioned in a crossing arrangement with the first lines, a crosspoint location being defined where each first line crosses each second line. An electrically programmable impedance memory element is positioned at each crosspoint location and is electrically coupled between the first and second lines corresponding to that crosspoint location, each impedance memory element having an electrically programmed state. The composite material modulates the radiation beam according to the electrically programmed states of the impedance memory elements.

    摘要: Apparatus and systems are provided for data signaling between a centralized transceiver and a plurality of sensor nodes. Each sensor node independently generates electrical power from one or more renewable sources. Each sensor node transmits data corresponding to sensed physical variables to the transceiver by free-space signaling. Large areas can be monitored by a vast array of such sensors without the need for wiring, optical fibers or other tangible interconnections.

    摘要: A memcapacitor device (100) includes a first electrode (104) and a second electrode (106) and a memcapacitive matrix (102) interposed between the first electrode (104) and the second electrode (106). Mobile dopants (111) are contained within the memcapacitive matrix (102) and are repositioned within the memcapacitive matrix (102) by the application of a programming voltage (126) across the first electrode (104) and second electrode (106) to alter the capacitance of the memcapacitor (100). A method for utilizing a memcapacitive device (100) includes applying a programming voltage (126) across a memcapacitive matrix (102) such that mobile ions (111) contained within a memcapacitive matrix (102) are redistributed and alter a capacitance of the memcapacitive device (100), then removing the programming voltage (126) and applying a reading voltage to sense the capacitance of the memcapacitive device (100).
