摘要： Examples of the present invention include a metamaterial comprising a plurality of resonators disposed on a substrate, the substrate comprising a dielectric support layer and a relatively thin semiconductor layer, having a Schottky junction between at least one conducting resonator and the semiconductor layer. The properties of the resonator may be adjusted by modifying the physical extent of a depletion region associated with the Schottky junction.

摘要： A beam-steering system having high positional resolution and fast switching speed is disclosed. Embodiments of the beam-steering system comprise a diffraction limited optical system that includes a reflective imager and two controllably rotatable MEMS elements. The optical system is characterized by a folded optical path, wherein light propagating on the path is incident on each MEMS element more than once. Each MEMS element imparts an optical effect, such as angular change, on the output beam. By virtue of the fact that the optical system is multi-bounce optical system, the optical effect at each MEMS element is multiplied by the number of times the light hits that MEMS element.

摘要： A quantum-dot photon turnstile device is capable of producing a stream of regulated and directed single pairs of photons with opposite circular polarizations. This device operates by injecting pairs of electrons and holes, alternately, into a single quantum dot, where they combine to form photons. The device will efficiently and reliably produce a directed beam of such photons at regular time intervals. It will be able to operate at high frequency and at high temperature. Such a stream of regulated photon pairs will be useful in quantum cryptography, quantum computing, low-power optical communications, as a light standard, and in many other areas of technology and fundamental science.

摘要： Cellular signals or other wireless signals/messages are introduced into a building or to an outside location by transmitting packets corresponding to those signals over a data network and low cost cables to designated locations within the data network. Once the designated packets containing the signals reach the destination, they are then broadcast over the air to a terminal capable of receiving the wireless message. In a first embodiment, an in-building gigabit Ethernet network, such as that currently existing presently in many buildings, is used to distribute radio signals indoors. Instead of transmitting the radio signals over the air from a repeater connected to a base station, coded baseband signals generated by the coding processor (e.g., a CDMA Modem Unit) in the base station are packetized and sent over the Ethernet network to radio processing equipment and antennas distributed throughout the building. The radio processing equipment strips the packet headers from the baseband signal packets so those signals can be broadcast via the antennas to one or more mobile terminals.

摘要： A packaged MEMS device containing the micro mirrors has mounted on it at least two distinct integrated circuit chips, at least one of which contains the low-voltage digital-to-analog converts and at least one of which contains the high-voltage amplifiers. The integrated circuit chips may be mounted directly to the MEMS package, or they may be indirectly mounted thereto, e.g., by being directly mounted to a multi-chip module which is in turn mounted on the package. Thus, the MEMS package is employed in a dual role, 1) that of package for the MEMS device and 2) the role of a backplane in that it contains mounting places and the wires interconnecting the MEMS device and chips or modules containing the low-voltage digital-to-analog converters and the high-voltage amplifiers.

摘要： A new bulk resonator may be fabricated by a process that is readily incorporated in the traditional fabrication techniques used in the fabrication of monolithic integrated circuits on a wafer. The resonator is decoupled from the wafer by a cavity etched under the resonator using selective etching through front openings (vias) in a resonator membrane. In a typical structure the resonator is formed over a silicon wafer by first forming a first electrode, coating a piezoelectric layer over both the electrode and the wafer surface and forming a second electrode opposite the first on the surface of the piezoelectric layer. After this structure is complete, a number of vias are etched in the piezoelectric layer exposing the surface under the piezoelectric layer to a selective etching process that selectively attacks the surface below the piezoelectric layer creating a cavity under the resonator.

摘要： A metamaterial microwave lens having an array of electronic inductive capacitive cells in which each cell has an electrically conductive pattern which corresponds to incident electromagnetic radiation as a resonator. At least one cell has a first and second electrical sections insulated from each other and each which section has at least two legs. A static capacitor is electrically connected between one leg of the first section of the cell and one leg of the second section of the cell. A MEMS device is electrically disposed between the other legs of the first and second sections of the cell. The MEMS device is movable between at least two positions in response to an electrical bias between the first and second sections of the cell to vary the index of refraction and resonant frequency of the cell.
