Applied Quantum Technologies proposes the development of a snapshot Raman spectral imager for chemical imaging applications with a 1-5 meter standoff. Standoff chemical imaging methods are typically point-based, making scan times impractical for situations where a wide area needs to be surveyed. The high spectral resolution needed to take advantage of the specificity of Raman spectroscopy limits t ...

The technology, theory and fabrication of metamaterials have seen impressive progress in the last few years, and various applied fields have benefited from the flexibility of electromagnetic response that metamaterials provide at microwaves, infrared (IR) and/or optical frequencies. Negative-refractive and zero-permittivity metamaterials have been proposed for breakthrough novel applications in m ...

ABSTRACT: Airborne directed energy weapons offer advantages over conventional weapons as they minimize collateral damage, reducing the cost of post-conflict reconstruction. However, the high power levels required by these weapons present size and weight challenges for airborne applications. In particular, the current capacity required of the power transmission cables can make them one of the heav ...

ABSTRACT: The potential of scramjet engines for use by the U.S. military would revolutionize countermeasures enabling rapid responses to global hot spots. The scramjet traveling at hypersonic speed cannot use rotary power typically employed at sub-Mach velocities, while auxiliary power units and batteries add weight, volume, and system complexity. Thus, alternative power sources are sought to ai ...

For the U.S. Navy, Creare is developing a Compact Swaging Machine (CSM) to attach arresting gear Purchase Cable terminals on ship. Our CSM utilizes three innovative features to dramatically reduce the size and weight of the swaging machine to make it usable in a shipboard environment: (1) a high pressure hydraulic system which minimizes the actuator size, (2) an efficient swaging schedule which re ...

Wave Computation Technologies and Duke University will develop minimally coupled, co-mingled E and B field antennas through numerical and experimental investigations based on first-principle theories. The project objectives are to (a) develop the simulation capability for modeling superconducting quantum interference filter devices and the related B field antennas, (b) make appropriate designs of ...

The Tai-Yang Research Company in partnership with the Center for Advanced Power Systems at Florida State University proposes to develop a warm-to-cold electrical termination for a cryogenically cooled high temperature superconductor cable. The termination will be optimized for the requirements defined by the Next Generation Integrated Power System. The proposed termination will include a novel met ...

Future military communication systems will rely on advanced superconductor digital electronics. These electronics will require efficient cooling at low temperatures near 4 K. Pulse-tube cryocoolers are a candidate cooling technology for this application. We propose to improve the efficiency of the pulse-tube cryocooler by addressing one of its primary performance limitations, namely the performanc ...

The performance of modern combustion systems used in propulsion devices (such as gas turbine main combustors, augmentors, and rockets) is largely dependent on the mixing of fuel and oxidizer. This mixing process, often involving a liquid jet emanating into a gaseous flow followed by subsequent breakup and atomization, is critically important to many performance metrics including thrust, efficiency ...

In miniature gas turbines for UAV applications, traditional bearings exhibit a typical lifetime of only 25 hours due to excessive axial loading. Mainstream proposed a passive permanent magnet thrust bearing to alleviate this problem and increase service life to over 1000 hours. Since this type of bearing is non-contacting, it can operate at very high rotational speeds with minimal heat generation ...
