"This Small Business Innovation Research Phase I project will investigate a promising new technique for fabricating periodic domain gratings in stoichiometric lithium tantalate(SLT). The key innovation in this SBIR effort is the use of externally mountedmicro-electrodes to electrically pole the material. This poling technique, made possible because of the low coercive field found in SLT, will sign ...

"A low-cost chemical solution derived material is being proposed as an environmentally-friendly corrosion resistant coating material to combat the corrosion problems faced by the MDA. The coating material is a newly discovered inorganic oxide, calledCerablak, which is amorphous, or glassy, in nature and can be deposited as a hermetic, dense, and pin-hole free film by a simple dip coating, paintin ...

"In a network stack Denial-of-Service (DoS) attack, numerous network packets flood the packet queues on a computer system, rendering the processing software on that machine (the "network stack") incapable of processing normal traffic. (This is not the sameas a network bandwidth attack, in which copious packets overwhelm the capabilities of the data lines in and out of the computer.)We propose to ...

"The primary objective of CU AerospaceOs Phase I work will be to develop all-gas-phase closed-cycle electrically assisted COIL (ElectriCOIL) technology. CU Aerospace (CUA) and the University of Illinois at Urbana-Champaign (UIUC) believe that thischallenge can be surmounted with changes to gain generator research including 1) radically new O2(1D) generator subsystems which are amenable to closed- ...

"Composite cryogenic storage tanks will enable ABL and SBL program objectives by reducing structural weight, increasing reactant mass, reducing systems costs, and reducing risk to the programs. A recent development in composite materials design formultifunctional damage mitigation is proposed as a solution to the microcracking problem for composite tanks for storage of cryogens. By incorporating ...

"Avalanche photodetectors (APD) focal plane arrays (FPAs), with high sensitivity and large dynamic range are the most promising photodetectors for three dimensional imaging LADAR systems due to their low detectable powers and high performance. However, manypresent-day devices have poor bandwidths and noise properties because they exhibit comparable electron and hole impact ionization coefficients. ...

"High-performance HgCdTe focal plane arrays (FPAs) sensing in the long-wavelength (LWIR) and very long wavelength (VLWIR) infrared spectral ranges are highly desirable for various applications supporting missile defense capabilities. Advanced sensorstructures based on dual or multi-color HgCdTe IRFPAs will enhance early missile threat detection while providing mid-course tracking capabilities and ...

"A drastic reduction in structural weight is an indispensable prerequisite to realize future Theater High Altitude Area Defense (THAAD) systems. Boost Defense segments of the program such as the Airborne Laser (ABL) and Space-Based Laser (SBL) require thestorage and transport of large amounts of cryogens. All elements contributing to the cryogenic system mass must be as light as possible. Advanc ...

"A novel method of micro-mixing by inducing a low frequency resonant sonic vibration (LFRSV) in the fluid medium results in the increased rate of energy dissipation per unit mass of the fluid, allowing rapid and efficient dispersion of solids, gases, andimmiscible liquids. This enhanced way of achieving micro mixing, can be used for dispersing nano particles in making gel propellants. Rheologica ...

"At present, the most promising technology for VLWIR focal plane array applications is III-V compound semiconductor superlattices based on arsenides and antimonides, such as type-II InAs/GaSb, because of their much larger area and bandgap uniformity, andhigher operating temperatures than currently available technologies. It is here proposed to study the feasibility of innovative nanostructures in ...
