ABSTRACT:In this effort, we will couple the energy of focused microwave bursts into the air and onto surfaces by first forming a laser plasma. The presence of the laser plasma allows much lower microwave intensities to couple their energy to the laser-pre-ionized surface or air- volume, allowing more efficient energy-transfer and the use of lower-power microwave systems to achieve the desired effe ...

ABSTRACT: A phase II program is proposed leading to integrate wireless inductive power transfer technology on two prototype tactical vests. The focus of the phase II program would be the development and evaluation of a full-scale inductive power transfer system on a PRC-152 radio by both modifying and interfacing its battery. Because a mating vest/pouch that contains inductive charging circuits so ...

ABSTRACT:Todays analysts need improved 3D visualization tools to assist in critical situations such as deconfliction, line-of-sight analysis, air space and satellite control.Currently available 3D displays cannot provide the level of detail and comfort needed because the displays contain unacceptable visual artifacts, do not provide full parallax, require special headgear, and induce nausea in man ...

ABSTRACT: Silicon-based lasers/detectors have long been desired for owing to the possibility of monolithic integration of photonics with high-speed Si electronics and the aspiration of broadening the reach of Si technology by expanding its functionalities well beyond electronics. The goal of this project is to first develop high quality SiGeSn material and then use it to demonstrate prototype opt ...

ABSTRACT: Si photonic devices based on GeSn materials will be very important for the MWIR. The Air Force recognizes the need for next-generation high-performance photonic materials in the SWIR to MWIR infrared spectrum, due in part to the atmospheric high transmissive windows in this wavelength ranges. Due to materials limitations, silicon based photonic devices have not been utilized in this wa ...

Advanced thick composites are increasingly used in components for defense applications as well as commercial structures. The proposed project will lead to the development and commercialization of a validated predictive capability based on the Peridynamic (PD) theory to enhance the performance of thick composite components under complex loading conditions while exposed to harsh environments. The pr ...

Hypersonic vehicles are strategic weapon systems in the Navy arena. Hypersonic vehicles require erosion-free sharp leading edges with a 0.04 inch radius which must exhibit 30 minute operation at 4500F (2482C). It has not been demonstrated to 3D weave fibers into a sharp leading edge architecture of 0.04 inch radius, nor prevent erosion of a leading edge at hypersonic flight conditions for 30 minut ...

There is a need for new types of IMUs, with better accuracy than the state of the art. Digital Optics Technologies (DOT) has been developing a Fast Light Optical Gyroscope (FLOG) that can improve the accuracy of rotation sensing by nearly six orders of magnitude. Alternatively, for a given accuracy need, the FLOG can be very small. DOT has also developed a Fast Light Optical Accelerometer (FLOAC ...

We propose the development of long wavelength infrared (LWIR) sensors based on HgCdTe in a novel noise-suppressing high temperature barrier (HTB) architecture, which combines the benefits of unipolar nBn and non-equilibrium, Auger-suppressing high operating temperature (HOT) structures. The proposed design is beneficial for controlling carrier conduction to minimize the number of majority and min ...

Absorber layers based on Type-II superlattices (T2SLs) composed of III-V compound semiconductors (e.g. GaSb and InAs) are a promising sensor technology for infrared imaging; however, dark currents and short carrier lifetimes in the Ga-containing T2SL are significant problems. It is presently suspected that the short carrier lifetimes and some dark current arise due to a native point defect, possi ...
