  • Optical coating
    Publication number: 20100246009
    Abstract: Optical coating materials comprise a transparent matrix material having dispersed nanoparticles comprising between 1 and 20 volume percent of the optical coating material. The coating materials are used to form optical coatings on substrates, such as glass/ceramic, polymer or metal, to alter the color or other optical properties. The nanoparticles are semiconductive material or elemental metals or elemental metal alloys that exhibit surface plasmon resonance.
    Type: Application

  • Tunable dielectric radio frequency microelectromechanical system capacitive switch
    Patent number: 7786820
    Abstract: The invention is a tunable RF MEMS switch developed with a BST dielectric at the contact interface. BST has a very high dielectric constant (>300) making it very appealing for RF MEMS capacitive switches. The tunable dielectric constant of BST provides a possibility of making linearly tunable MEMS capacitive switches. The capacitive tunable RF MEMS switch with a BST dielectric is disclosed showing its characterization and properties up to 40 GHz.
