RECENT ADVANCES IN HIGH TEMPERATURE SUPERCONDUCTING (HTSC) THIN FILM TECHNOLOGY ENABLE THE FABRICATION OF LOW-LOSS COMPONENTS THAT WILL IMPROVE THE COST AND PERFORMANCE OF CHANNELIZED RECEIVERS. CHANNELIZED RECEIVERS ARE USED IN SATELLITE TRANSPONDER, ELECTRONIC WARFARE AND ELECTRONICS INTELLIGENCE APPLICATIONS AND ARE COMPRISED OF A GROUP OF NARROW BAND RECEIVERS THAT COVER INDIVIDUAL SLOTS IN A ...

SIGNIFICANT SIMPLIFICATION OF MICROWAVE PHASED ARRAY ANTENNA SYSTEM ARCHITECTURES CAN BE ACHIEVED WITH HTSC DEVICE TECHNOLOGY. ELIMINATION OF THE LOW NOISE AMPLIFIERS (LNAS) CAN BE ACCOMPLISHED THROUGH REPLACEMENT OF THE GAAS PHASE SHIFTERS WITH LOW LOSS HTSC COMPONENTS. A REDUCTION IN COMPLEXITY LOWERS BOTH SYSTEM WEIGHT ANDCOST. KEY TO HTSC TECHNOLOGY INSERTION IN PHASED ARRAY ANTENNAS IS THE DE ...

The ongoing explosion of microwave radar and communications systems calls for improvement in electronically scanned antennas (ESAs). However, current ESAs crafted from multiple individual elements are extremely expensive. Forming an antenna with integrated scanning and impedance matching elements on a single substrate using thin film technologies may decrease costs by up to two orders of magnitu ...

FERROELECTRICS (FE) HAVE A LARGE COMMERCIAL POTENTIAL AS PIEZOELECTRIC ELEMENTS, DIELECTRICS FOR CAPACITORS, AND IN OPTICAL GUIDED-WAVE DEVICES. MATERIALS PROCESSING HAS LIMITED APPLICATIONS IN MICROELECTRONICS AND PHOTONICS, HOWEVER, AND FEW METHODS ARE CAPABLE OF DEPOSITING HIGH QUALITY THIN FILMS COMPATIBLE WITH STANDARD SI INTEGRATED CIRCUIT PROCESS TECHNOLOGY. METALORGANIC CHEMICAL VAPOR DEPO ...

THIS PROGRAM'S OBJECTIVE IS TO ESTABLISH THE RELAXOR FERROELECTRIC PB(MG1/2NBS/3)O3 (PMN) AS THE MATERIAL OF CHOICE FOR THIN FILM CAPACITORS IN DRAM AND ELECTRONIC PACKAGING APPLICATIONS.IN CONTRAST TO "NORMAL" FERROELECTRICS, E.G., BATIO3 AND PZT, RELAXORS OFFER HIGH DIELECTRIC CONSTANTS (K>10,000), BROAD PHASE TRANSITIONS,LOW E-FIELD DEPENDENCY OF K, AND LARGE RXC TIME CONSTANTS. IN ADDITION, TH ...

The TRP-SBIR project will address the synthesis and characterization of single crystal relaxor ferroelectrics for high performance bio-medical transducers. The ability to grow single crystals of various relaxor-based compositions with specific crystallographic orientations offers piezoelectric, dielectric and electro-mechanical properties not achieveable in ploycrystalline PZT ceramics. Limitati ...

This SBIR Phase I program will address the fabrication and testing of voltage variable dielectrics (VVD) in which the refractive index (n) can be E-field tuned providing electronic scanning in the microwave regions. In collaboration with Hughes' Radar Division, the manufacturing of large area composites based on the perovskite Barium Strontium Titanate (BST) will be integrated into a continuous t ...

This SBIR Phase I program will address the fabrication and testing of pseudo single crystal relaxor ferroelectrics (PMN:PT) for high performance electromechanical actuators. In collaboration with Innovation Powder Technology, Inc. the crystallographic orientation of solid state grown PMN:PT will be controlled using hydrothermally synthesized perovskite PbTiO3. The use of large 5-10 micron platel ...

We propose the development of a system for visually tracking and interpreting human motion for the purpose of controlling devices, interacting with virtual worlds, and interpreting overhead reconnaissance video data. That is, we intend to implement a gesture recognition and device control system. In many application, using gestures for device control is more practical than other forms, such as s ...
