Research in visualization of multi-int data to improve the fusion process has taken recently taken on multiple approaches. In particular, link analysis diagrams have become popular for visualizing relationships between friendly, threat, unknown and NGA entities. Link analysis diagrams, while powerful, are often difficult to input data, navigate, filter and visualize content. They often are not int ...

This project will determine a means of focusing blast waves from volumetric explosives such as thermobaric and vapor cloud explosions. The work will be carried out using a combination of numerical and experimental approaches and will produce a first optimization of the selected solution.

Accurate numerical predictions of performance of antennas on aircraft are important in many problems of avionics design and integration. In particular, such predictions are needed for determination of optimal placement of antenna on an aircraft in order to achieve required coverage. The focus of this project is an investigation and development of high-frequency computational methods and codes for ...

Cermet, Inc in collaboration with Georgia Institute of Technology proposes to develop spin Light Emitting Diode (LED) in a 24 month Phase II program. The spin LED is a simple yet powerful spintronic device that produces circularly polarized light and is a potent tool to quantify the spin injection efficiency and spin polarization efficiency.

The goal of this effort is to grow n and p ZnO thin films by MOCVD on ZnO substrates. The primary objective of this phase I effort will be to grow p-n homojucntion and characterize the LED structure. Bandgap of ZnO will be engineered and heterojunction quantum wells will be grown. The grown device structures will be characterized for structure and quality by X-ray, PL and electron microscopy, The ...

The goal of this program is to develop ZnO based light emitters fabricated on high quality ZnO bulk substrates. The work will focus on enhance doping of the active layers, target alloy concentrations and prototype emitter fabrication.

Crossfield proposes to develop a hybrid direct write technique for developing conformal circuits and semiconductors. Crossfield, together with Honeywell and the Massachusetts Institute of Technology (MIT) intend to demonstrate a conformal circuit technique that enables the metal elements of the circuit (such as power and signal traces or antennas) and supporting semiconductors such as bias circui ...

Crossfield proposes a high dynamic range, ultra-wideband, receiver-digitizer that will enable implementation of a compact UWB target identification system for the detection and location of targets and weapons concealed behind walls or foliage or hidden on a person. The design features an ultra-wide bandwidth, high dynamic range sampler developed by Picosecond Pulse Labs, followed by a track-and-ho ...

Crossfield Technology proposes an innovative direct conversion receiver and digital signal processor system that provides ultra wideband frequency coverage at ultra high frequency resolution. Key features of Crossfield's ultra wide band receiver and signal processor design include: Ultra wide band direct conversion (zero-IF or near-zero-IF) using state-of-the-art SiGe analog-to-digital convert ...

There is a need for a low profile, simple, accurate, localized, responsive sensor to measure shear stress in fluid flow. The unusual properties of shape memory alloys, and of Ni2MnGa in particular, suggest they could be sensing elements for shear. In recent years, single crystal films of Ni2MnGa have been grown by Molecular Beam Epitaxy (MBE). Once released from their substrate, these films hav ...
