To streamline data processing in, e.g., hyperspectral imaging, new massively parallel data processing circuits are needed. The team of MicroXact Inc. and UC Santa Barbara propose to develop circuits based on completely novel computing paradigm, which could be extremely efficient (i.e. dense, relatively inexpensive, and consume very little power) for massively parallel signal processing. We offer t ...

Over the past 2 years, Roccor has successfully qualified and delivered High Strain Composite (HSC) products for space-flight customers including, 1) RF-Furlable boom, 2) a furlable-antenna system; and is currently qualifying HSC products for space-flight customers including 3) an FCC certified deorbit device, and 4) a solar array deployment system. Three of these missions will be launched in 2018. ...

Wave-optics simulations are critical tools for analysis of laser directed energy systems. The primary method for conducting these simulations is to evaluate the Fresnel diffraction integral using the angular spectrum method based on the fast Fourier transform (FFT). While FFTs are considered computationally efficient, their use in the Fresnel integral results in difficult grid constraints includin ...

We propose to demonstrate and advance several key aspects of our novel, scalable ammonothermal technology for growth of high quality single crystal gallium nitride. Specifically, we propose to demonstrate a high growth rate and high crystalline quality, to design and analyze a pilot-scale reactor, and to construct and validate a quantitative model to describe the fluid dynamics of the growth envi ...

The SEAKR team proposes to continue development of the advanced protocol routing system begun in the Phase I effort, to reduce risk toward a flight deployable system for SATCOM assets such as Iridium NEXT. SEAKRs development of the Iridium NEXT modem...

Quantum computer technology is so critical and strategic that the Air Force Research Laboratory is itself working on a quantum bit focused on the trapped ytterbium (Yb+) ion. The current technology based on entangling electrons, photons, or ions are challenging to put together in multiple qubits. To make a qubit stable, it is essential to protect it from outside interferences that can disrupt the ...

Unmanned aircraft systems (UAS) are increasingly seen as a cornerstone in developing the future Defense infrastructure and it is critical that they collaborate efficiently and execute complex missions in denied environments. Although great progress has been made in GPS-denied navigation, the target handoff problem in GPS-denied environments has not been extensively studied. In this problem, a trac ...

The objective of this project is to develop a practical finite element-based simulation of spin-pit tests of disks. The performance of disks in spin-pit tests critically depends on localized effects, such as residual stresses, dislocations, and microstructure gradients. Therefore, a two-scale modeling approach is adopted. At the global-scale, the disk is represented by means of finite elements wit ...

ABSTRACT: Infrared sources and sensors are becoming increasingly useful for military and commercial applications. We propose to exploit recent advances in multimaterial fiber technology to produce a new class of optical infrared fibers that are robust and low in cost for high-power, high-stress environments. The use of beam confining fiber optics reduces or eliminates issues with misalignment or d ...

ABSTRACT: Chalcogenide glass fibers are commercially available and are used for delivery of mid-infrared wavelengths (1.5um to 6.5um).These fibers allow compact, robust and low-weight laser platforms designs.Laser systems in high-power and high-stress environments find their reliability and performance limited due to free-space optical components.Free-space components suffer from vibration and the ...
