The invention is a tunable RF MEMS switch developed with a BST dielectric at the contact interface. BST has a very high dielectric constant (&#x3e;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.

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.

Electronic and optical devices and methods of forming these devices

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 () to another () and can be varied in all three directions. Methods of producing the composite materials and waveguides are also disclosed.

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.
