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: 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 ...

ABSTRACT: Oceanit proposes to develop multiphase composite materials using shockwave consolidation approach. New materials will have exceptionally high mechanical strength, thermal and electrical conductivity as compare to current state-of-art technology. Oceanit"s prior experience in designing and fabricating novel will be critical in the success of the proposed effort. BENEFIT: Design future ...

ABSTRACT: U.S military logistics fuels such as JP-8 and JP-5 are used across the full range of its IC engines, from those adapted from Avgas to Remove Piloted Aircraft (RPA) applications to heavy duty compression ignition engines. Yet unlike commercial diesel fuels, these distillate fuels have no cetane specification, and so vary widely in this key measure of ignition delay. The result can be s ...

A missile will sometimes break into smaller pieces, either by design or as a result of a malfunction or collision. The latter cases are called off-nominal, and can be difficult to analyze, especially if not observed directly. Before break-up there is a single parent object. After break-up there are multiple child objects, likely on very different trajectories. A radar is assumed to track the p ...

Oceanit will develop an antenna-integrated electromagnetic (EM) sensor IC to measure a weak magnetic field around a field programmable gate array (FPGA). The device will be able to operate on very low power and withstand g forces during acceleration, vibrations from air and ground vehicles, and high/low temperatures experienced during flight and ground operations. Approved for Public Release 14- ...

ABSTRACT:Ultra-stable and accurate frequency and timing devices such as atomic clocks are essential for modern communication, navigation, surveillance, and missile guidance systems. There are many atomic oscillators such as neutral calcium and neutral ytterbium that produce clock signal in optical domain. However, these optical standards are expensive and not widely available. The phase stabilized ...

The reliability of electronic packages is of paramount concern in todays electronics industry, and ensuring their thermomechanical integrity is necessary to achieve this reliability. However, this task has become more challenging with miniaturization and the introduction of new materials. Thermal stresses in electronic packages continue to be one of the leading causes of device failure. The pro ...
