This Phase I project is to investigate the feasibility for achieving EUV detectors for space applications by exploiting the ultrahigh bandgap semiconductor - AlN. We plan to devise methods to improve the AlN epitaxial material quality and device structures for EUV detectors. Specifically, we will study the properties of Si and Mg doped AlN epilayers and investigate n- and p-type doping issues in ...

Fastening and joining technology has lagged behind the progress that has been made in other areas of composites for advanced air vehicles. Aerotech proposes the development of reversible polymeric adhesive bonding of composites using variable frequency microwave energy. With this method, composites are bonded using Poly Ether Ether Ketone (a high temperature thermoplastic) which is cured using v ...

Agricultural mulch films are used for the production of vegetables and fruits. Thin plastic films (typically polyethylene) are spread along the rows of plants at the beginning of the growing season. Holes are made in the films to plant the seeds or seedlings. The use of mulch films speeds the ripening of crops, conserves moisture and fertilizer, and inhibits weed growth, fungus infection and insec ...

This is a Phase II proposal to continue the work begun by AgriTech Electronics, LC (AgriTech) on a GPS-based livestock control system. This system will exclude animals from areas, or contain them within defined boundaries, where it is impractical or inefficient to build fence to achieve this objective. These needs arise in a variety of contexts, including the exclusion of livestock from riparian a ...

The overall objective of this effort is to address a nagging void in the study of Information Age Warfare: there is no coherent set of tools that military analysts can use to visualize, measure, understand and asses networked military systems. While there has been a great deal of effort expended to develop tools in academia (and to a limited extent for commercial business), these products tend to ...

Overbey, Jr., Principal Investigator Mr. William K. Overbey Jr., Business Official DOE Grant No. DE-FG02-98ER82528 Amount: $74,694 Many fractured gas reservoirs could be produced ...

The electromagnetic directed energy method (lasers, particle beams, and high power microwaves) of defending against missiles relies on generating a large amount of energy at the defense site, locating the target, and then transporting a large fraction of that energy to the target along a line of sight at the speed of light, to either destroy or destabilize the threat at as long range as possibl ...

New missions require that airborne radars operate at increasing ranges with higher target resolution. This combination necessitates the cost-effective deployment of large apertures while maintaining aerodynamic performance. Externally mounted antenna arrays are not a satisfactory solution due to the large size at low frequencies, for example with UHF foliage penetration radar. Another approach emp ...

The objective of the proposed effort is to develop a digital beamforming (DBF) processor capable of generating multiple simultaneous receive beams with a wide (>500 MHz) instantaneous bandwidth (IBW). This would offer a significant improvement over a similar DBF processor with 15 MHz IBW that Applied Radar, Inc. previously developed for AFRL. The wide bandwidth is necessary for a number of high-re ...
