Abstract:
Tunable radio frequency (RF) devices, such as phase shifters and filters, are formed by depositing thin film layers on a substrate and patterning the thin film layers by various lithography techniques. A thin film metal layer is patterned to form a plurality of capacitors and inductors, leaving at least two grounding regions that lie closely adjacent the capacitors and inductors. As patterned portions of the grounding regions are electrically isolated from each other. Performance of the devices are improved by electrically bridging the differential potential grounding regions.
Abstract:
Hydrophobic and self-cleaning surfaces have wide applications, including glasses, camera covers, windows, solar panels and high-end finished surfaces. Many existing hydrophobic coatings either have low transmittance, making them unsuitable for high light transmission applications, or are insufficiently hydrophobic. The present invention concerns high-quality hypertransparent superhydrophobic coatings, for example SiO2-based, with double-roughness microstructure that were deposited on to, for example, glass substrates using, for example, the combustion chemical vapor deposition (CCVD) technique. Embodiments of the invention include coatings with a contact angle of higher than 165°, a rolling angle of
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.
