The objective of the proposed research is to develop new technologies and a prototype of the Time Reversed Acoustics (TRA) system of land mine detection. This system provides a high concentration of seismic wave energy at any desired point (e.g., on a land mine). It is the only system that is capable of focusing seismic waves in time and space, which highly increases the detection abilities of lin ...

Caviton has developed a novel technique for the continuous monitoring of trace metals emissions. This technique is based on a microdischarge light, which is collected by a spectrometer and analyzed. All metals tested to date can b detected and the focus of this Phase II project is to develop a sampling system, carry out laboratory tests, then move to field tests of sampling and analysis. Finall ...

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 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.

A critical operational problem for Army rotorcraft is “brownout” caused by excessive dust and debris kicked up by helicopter rotorwash during take-off and landing. This can eliminate visibility and severely damage engine parts and rotor blades. Brownout is causing significant hazards for helicopter operations in Iraq and Afghanistan. The proposed effort will develop a physics-based aerodyna ...

Detection and identification of similar class military targets can be extremely difficult, especially at extended ranges. The wide variety of deployment scenarios further complicate this effort. In reality, the sensitivity of an imaging system and the contrast of targets can be strongly reduced. There have been several approaches (hardware solutions) to overcome the problem of optical image degra ...

The use of Si-based composite substrates for HgCdTe infrared focal plane arrays holds the promise of improved resolution, greater robustness and lower cost as compared to arrays that employ the present-day standard CdZnTe substrates. The principal challenge associated with the use of Si-based substrates is the presence of dislocations, created by the large lattice mismatch, that thread into the Hg ...

In this work, we will demonstrate military specification compatible 1.8 - 1.85 µm InP-based diode pump laser arrays with a power output exceeding 10 W, the critical milestone necessary to enabling system insertion. These sources can help in the critical development of a variety of military and home security applications, including optical pumping sources for 3-5 µm lasers, chemical sensing, las ...

SBIR Phase-I program investigation into a Wide Band Gap (WBG) technology and its ability to meet the Air Force specifications for a High Power Amplifier (HPA) demonstrated unequivocally the feasibility of meeting/exceeding this objective with GaN HEMT devices. The 50W power achievable over a multi-octave bandwidth of [200MHz-1,000MHz] and [1,000MHz-4,000MHz] with efficiencies [PAE] exceeding 40%, ...

The Objective of this proposal is to continue the development of the innovative fuel filter design that combines a water-selective membrane technology, spiral-wound filter design, and cross-flow filtration. In Phase I, the feasibility of these design features was demonstrated. Phase II will pursue advanced development to refine the design, optimize the performance, and build several 16.5 gph membr ...
