Aurora and Georgia Tech"s Phase I efforts demonstrated the feasibility of a partially distributed control scheme with separate controllers on the engine core and fan, where the controllers are linked by a supervisory controller. This scheme is representative of the situation encountered in VTOL UAV design and the design of new turbo-props and variable pitch turbofans by the large commercial gas t ...

Two-dimensional (2D) visualization techniques have limit capacity to achieve understanding of full dimensionality of the battlefield. Rewritable 3D holographic storage is promising for updatable 3D display applications. In Phase I, New Span Opto-Technology has demonstrated novel concepts of both holographic recording technique and recording material system without the use of high voltage. We have ...

ABSTRACT: EDEN PARK ILLUMINATION, INC. and the University of Illinois have formed a team to pursue the demonstration and commercialization of large arrays of microcavity plasmas capable of producing white light panels with luminous efficacies above 30 lumens/W. This proposed project will demonstrate the ability of arrays of microplasmas to yield flat lamps of high efficiency, luminance, and col ...

GaN-based devices are the basis of a variety of modern electronics applications, especially in optoelectronics and high-frequency / high-power electronics. These devices are based on epitaxial films grown on single-crystal wafers. The single-crystal wafer substrates are limiting because of their size, expense, mechanical properties and availability. If one could make GaN-based devices over large a ...

This Small Business Technology Transfer Phase I project will develop ultradense, low-power plasmonic integration components and devices for on-chip manipulation and processing of optical signals. Both passive and active components will be studied. Detailed performance predictions will be obtained through finite element modeling (FEM) of the harmonic Maxwell’s equations. The FEM provides detai ...

Digital electronics is approaching its limits in meeting the demand for increased processing speeds. Photonics, while promising high processing speed, is lacking integration capacity. Plasmonics promises to combine the information capacity of photonics with the integration density of electronics. The team of Luna Innovations, UCLA and Virginia Tech proposes to develop plasmonic logic devices and c ...

Photovoltaics, while promising clean and reliable energy source, is not yet compatible with fossil energy for most applications. Organic-based solar cells have potential to reduce the cost of solar energy due to low-cost active materials, high-throughput reel-to-reel deposition technologies, low-temperature processing and application versatility. Currently organic photovoltaics (OPV) cannot commer ...

Nonlinear transmission lines offer new vistas in the generation of high power microwave wave (HPM) signals. All electromagnetic sources use an active medium to convert electrical energy to high frequency waves and ultra-wide band signals that can perform useful work. Traditional methods rely on electron beams for the active medium. Nonlinear transmission lines use nonlinear circuit elements to ...

Industrial Control Systems (ICS) are critical elements in electrical, water, oil/gas, and manufacturing services involving supervisory control and data acquisition (SCADA), distributed control systems (DCS), and programmable logic controllers (PLCs). These systems allow operators to monitor sensor data and remotely control field devices. Initially, these devices were designed for closed-network or ...

Higher efficiency solar cells are needed to reduce solar array mass, volume, and cost for Air Force space missions. Intermediate-band quantum-dot (QD) solar cells can yield dramatically higher efficiencies than current multi-junction (MJ) technologies. However, several issues must be addressed to demonstrate manufacturable, high efficiency devices. CFDRC aims to develop: 1) High-efficiency, ligh ...
