  • 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.

  • 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.

  • Patent number: 7315662
    Abstract: Electronic and optical (or photonic) devices with variable or switchable properties and methods used to form these devices, are disclosed. More specifically, the present invention involves forming layers of conductive material and dielectric material or materials with varying conductivity and indexes of refraction to form various electronic and optical devices. One such layer of adjustable material is formed by depositing epitaxial or reduced grain boundary barium strontium titanate on the C-plane of sapphire.

  • Patent number: 6954570
    Abstract: Optical waveguide composite materials and integrated optical subsystems with low loss connection to optical fibers, are disclosed. The waveguide material has a varying thickness and/or refractive index from one portion (816) to another (820) and can be varied in all three directions. Methods of producing the composite materials and waveguides are also disclosed.

  • Patent number: 6939576
    Abstract: Coatings, particularly thin films, of polymeric material are produced in accordance with the invention by applying a finely divided aerosol of polymer solution to a substrate and substantially simultaneously applying an energy source to the applied solution to apply the solution. In cases where the polymer is cross-linking, the energy source assists in cross-linking of the polymer. The preferred energy source is a flame that may optionally or desirably deposit material along with the polymer spray. One particular aspect of the invention is directed to production of polyimide films. In accordance with another aspect of the invention, the co-deposition process is used to provide thin polysiloxane coatings on glass and other substrates.

  • Publication number: 20030215644
    Abstract: Coatings, particularly thin films, of polymeric material are produced in accordance with the invention by applying a finely divided aerosol (N) of polymer solution to a substrate (30) and substantially simultaneously applying an energy source (38) to the applied solution to apply the solution. In cases where the polymer is cross-linking, the energy source assists in cross-linking of the polymer. The preferred energy source is a flame (38) that may optionally or desirably deposit material along with the polymer spray. One particular aspect of the invention is directed to production of polyimide films. In accordance with another aspect of the invention, the co-deposition process is used to provide thin polysiloxane coatings on glass and other substrates.
