  • Patent number: 9837953
    Abstract: A metallic-dielectric photonic crystal is formed with a periodic structure defining a plurality of resonant cavities to selectively absorb incident radiation. A metal layer is deposited on the inner surfaces of the resonant cavities and a dielectric material fills inside the resonant cavities. This photonic crystal can be used to selectively absorb broadband solar radiation and then reemit absorbed radiation in a wavelength band that matches the absorption band of a photovoltaic cell. The photonic crystal can be fabricated by patterning a sacrificial layer with a plurality of holes, into which is deposited a supporting material. Removing the rest of the sacrificial layer creates a supporting structure, on which a layer of metal is deposited to define resonant cavities. A dielectric material then fills the cavities to form the photonic crystal.

  • Patent number: 9648532
    Abstract: The present invention relates to a method of transmitting and receiving data in soft handoff of a wireless communication system. According to an aspect of the present invention, in the method of receiving data in soft handoff of a wireless communication system, a mobile station receives a first sequence being generated by interleaving transmission data using a first interleaver pattern, and also receives a second sequence being generated by interleaving the transmission data using a second interleaver pattern. Then, the mobile station combines and decodes the first sequence and the second sequence before receiving an entire frame having the first sequence allocated thereto.

  • Patent number: 9494615
    Abstract: An encapsulated nanostructure fabricated using layers of polymer material and further processed for use in a micro-scale target device is presented. The fabrication includes the formation on a substrate of an array of encapsulated nanostructures. The encapsulated nanostructures each include a nanostructure and a micro-scale, multi-block structure that encapsulates the nanostructure. Each encapsulated nanostructure can be made usable by a target device by removing, e.g., by etching, one of the layers to expose a portion of the nanostructure.
