The primary objective of this proposal is to develop an understanding from first principles of the macroscopic particle force equation arising from the microscopic particle and field interaction dynamics and to incorporate those effects in a self-consistent state-space (rate equation) PIC calculation. Effective current and charge density time-domain equation models will ...

An important problem in the analysis of ATR systems is quantifying the growth of algorithm requirements, such as storage and processing cost, as the input problem l situation in classical complexity analysis, where the notion of input size is well-defined, there does not currenlty exist a clear notion of input size for the ATR problem. In this effort ...

Altair Center proposes to develop a novel and innovative compound-core multimode active flber for high-efficiency fiber laser systems capable to operate in a single-mode regime. The compound multimode core of the fiber is especially designed in such a way to support propagation of a higher order mode exhibiting a sharp peak of its field in the central region of the core. The sharp-peak mode extrac ...

The proposed program will develop a liquid crystalline Adhesive with Zero Shrinkage, for bonding of airframe joints. Aspen Systems, Inc. is currently in the process of developing a new class of epoxide resins. These new epoxy materials are based on orderable, low molecular weight liquid crystalline structures with flexible, difunctional end chains. The structural ordering of the liquid crystallin ...

This SBIR Phase I proposal is aimed at development of propulsion systems for EKV and divert. propulsion systems for low-mass interceptors that will use Vector Thrust Pulsed Detonation Rocket Engine (VTPDRE) technology. Use of PDRE will increase power density, enhance modularity, and reduce cost. Further improvements will be realized by introducing configurations with multiple PDREs and non-mechani ...

Gradient Technology in conjunction with Professor M. Hillmyer of the Department of Chemistry at the University of Minnesota proposed to develop advanced technology to recover and convert the explosive and urethane binder found in plastic bonded explosives. This technology provides a unique reclamation, recovery, and reuse opportunity for dramatically reducing the disposal cost of technology munit ...

The primary objective of this work is to determne the feasibility ofusing nitrogen doping to lower the trun-on voltage and improve the overall performance of GaAs-bsed heterojunction bipolar transistors (HBTs) for high frequency microwave applications. Recent reports on the properties of GaAs in which small amounts of N have been added indicate that GaAsN alloys possess a number of striking prope ...

We propose to develop a unifying framework and formalism for the rapid and novel design and implementation of new families of image transforms based on the theory of groups and diffraction geometry. Our approach calls on such high-level imaging tools as graphs and aperiodic tilings to relate image data geometry with group structures on image data indexing sets and complex group algebra theory to d ...

Current off-the-shelf Windows-based software/hardware data acquisition and control (DAC) systems are relatively slow, inflexible, and incapable of driving high speed, multi-channel systems. The proposed product will advance this technology through the development of an innovative, Windows-based Graphic User Interface (GUI) and required PC-resident module interfaced with a VXI chassis containing s ...

Time Domain Corporation proposes novel devices for achieving second harmonic generation in Laser Systems. The result will be a micro-size, layered, periodic, Semiconductor structure or a fiber Bragg grating that will perform several orders of magnitude better than devices in use today. Most second harmonic crystals that are currently used are of millimeter=size or greater. The simple design of ...
