The proposed effort will employ an array of broadband (W band) antennas, integrated with high-speed (subnanosecond) GaN HEMTs in an array, to detect potential threats to military personnel. The system will be low SWaP, low-cost, and will detect a NETD of 3 degrees or less, from at least 15 meters, with a pixel resolution of < 10 cm. Millimeter wave imaging has been shown to be a useful tool in the ...

A compact and portable SOFC, 1-3 kW, is an excellent choice to convert a hydrocarbon fuel source to electricity due to its high efficiency. Currently, SOFCs are optimized to run a single fuel source, and a fuel flexible reforming technique that can integrate with SOFC is needed to have the potential to utilize all different energy assets, including propane, methane, and biogas. Catalytic partial o ...

IntelliEPI IR, Inc. (IIR) and Sandia National Laboratory (SNL) propose to advance new avalanche photodetector (APD) technology using low-noise Aluminum Gallium Arsenide Antimonide (AlGaAsSb) based multiplication material and Indium Gallium Arsenide Antimonide absorber material and based on Sb-capable multi-wafer Molecular Beam Epitaxy (MBE) technology. Under this development effort, the team will ...

This project is to investigate chip-scale high power high brightness laser sources based on coherent photonic crystal surface-emitting laser (PCSEL) arrays. While high power VCSEL arrays are commercially available, they are incoherently coupled and multimode, with low beam quality and low brightness. To achieve coherently coupled VCSEL arrays, very large number of VCSEL elements are needed due to ...

TransWave Photonics, in collaboration with University of California, Santa Barbara, proposes to develop a photonic integration platform where high power diode lasers and coherent beam combining elements are monolithically integrated with high efficiency. Our estimation shows that more than 100 W peak power and 1 GW/cm2/sr brightness are achievable by implementing phased laser arrays more than 16 e ...

To achieve overmatch in C4I versus peer adversaries, Army intelligence analysts need support in detecting and classifying instances of adversary tactics, techniques, and procedures (TTP) execution across domains. Complex Event Processing (CEP) tools need improvement to meet this requirement, in order to detect entity behaviors and movements that may be observed by different sensors, or separated i ...

The new Bottom Attach munitions for the Close Terrain-Shaping Obstacles (CTSO) program, currently under development by the Army, requires that reserve batteries operate 30 days after activation in a low power sleep mode, while providing multiple high-power pulses. This operational profile requires batteries with energy and power densities beyond the limits of the current liquid reserve batteries. ...

The US Army is investing in the development of energetic materials for use in additive manufacturing (AM) for explosive and propellant applications in an ongoing effort to achieve extended range and lethality overmatch.  Currently, all commercially available monomers, polymers or resin systems for AM are non-energetic.  To use these in 3D printing applications for propellants and/or explosives, ...

The US Army and Department of Defense are continuing in their investment in the development of energetic materials for use in additive manufacturing (AM) for propellants.  Nalas Engineering is partnering with Dr. Lori Groven at the South Dakota School of Mines and Technology to develop innovative liquid resin systems for use in additive manufacturing, specifically UV light-based curing technol ...

Metal-organic frameworks (MOFs) are crystalline porous materials formed by the coordination driven self-assembly of metal ions/metal clusters and organic linkers. MOFs are attractive materials due to their tunable pore, very high surface area (up to 7000 m2/g), diverse possibilities of functionalization of the framework structure and potential applications. In particular, MOFs have showed potentia ...
