The design of future hypersonic vehicles requires detailed understanding of flow regimes ranging from rarefied to continuum. Hypervelocity flows are characterized by high temperatures, real gas effects, nonequilibrium chemistry, and ionization. The goal of this project is to develop unified kinetic/continuum solution methods with automatic domain decomposition for a wide range of Air Force applic ...

Photonic links and networks offer numerous advantages to analog RF systems including inherent wide bandwidth, a reduced size, weight and improved flexibility, and nearly lossless signal. Current all-electronic delay line systems based on microwave components suffer from high signal loss and dispersion as well as large size and weight. An efficient way to achieve true-time-delay beamforming is to u ...

Nanoscale infrared detectors are emerging as a potentially powerful alternative to traditional infrared detector technologies. The University of New Mexico has developed dots in a double well (DDWELL) quantum dot infrared photodetectors which have a spectral responsivity that can be tuned by controlling the bias voltage applied. In this Phase II effort, Polaris Sensor and UNM would fabricate a g ...

ABSTRACT: The goal of this phase II proposal is to develop a commercial platform for printing high performance, single-walled carbon nanotube transistor circuits on large-area plastic substrate. Automated processes will be developed for the room temperature printing of metal, semiconductor, and dielectric materials with micron-scale alignment accuracy. The transistor performance will be enha ...

The challenges faced by airborne and ground-based sensors in detecting, classifying, identifying, associating and tracking difficult moving targets, such as insurgent forces, operating in difficult terrain such as mountains and forests will be addressed. Our team will quantify the performance that can be achieved using multi-sensor, multi-spectral, and multi-platform techniques, where the sensors ...

The Phase I effort was successful in experimentally showing feasibility of a combined isotope transmitter that can be developed and demonstrated under the Phase II program. The initial experimental results give the window of gas mixtures for a stable discharge. Laser extraction tests were accomplished with C12/C13 mixtures to give guidance for further work to increase laser gain. For application ...

Results of the Phase I work showed that an advanced, compact Point Sensor can be built with good sensitivity for detection of both biological agents and chemical aerosol and vapor agents. This will be the first point sensor capable of this dual role. The
