This project is focused on the development of a new generation of GaN-based transistors with breakdown voltages in excess of 1kV that can be used in the demonstration of power amplifiers operating at 1 GHz with power added efficiencies in excess of 90%. To achieve this performance, this project will develop new approaches to increase the breakdown voltage of GaN high electron mobility transistors, ...

The low weight, excellent durability and heat resistance of ceramic matrix composites (CMCs) make them attractive materials for use in aircraft engine hot sections, where improved overall engine efficiency can be realized. Nevertheless, the interlaminar properties of CMCs must be well understood before CMCs can realistically replace metallic superalloys in engine hot sections, and no standardized ...

As strontium and other alkaline-earth metals become increasingly attractive for ultracold-atom applications, there is a growing need to develop compact, robust systems for cooling, trapping, and studying these elements. In this proposal, ColdQuanta will team with Dr. Jun Ye at JILA and the University of Colorado at Boulder to develop a portable, turn-key system that can produce, utilize, and optic ...

Wearable human state monitors must be mechanically invisible to greatest degree possible, to maximize comfort, wearability, hygiene and signal quality. These device attributes are aligned with the goal of closely coupling devices to the body for best-quality signal capture and continuous health monitoring by seamlessly integrating with the body, under clothing and gear. They must be robust to dyna ...

For Unmanned Aircraft Systems (UAS) to operate seamlessly in both the U.S. National Airspace System (NAS) and abroad, it will be crucial that they possess a sense-and-avoid (SAA) capability that can ensure safe operations among maneuvering, non-cooperative aircraft. Numerica Corporation, in partnership with Johns Hopkins University, proposes to develop a set of algorithms to model the uncertaintie ...

Continuous physiological monitoring can provide invaluable insight into the status of the person monitored. The right sensors can provide important information related to both the physical and mental state of the subject. Although sensing modalities and the information that can be gleaned from them is a fairly well advanced science, the sensors themselves lag behind in terms of being sufficiently ...

The proposed work will address the core physics underlying acoustic reverberation as related to properties of the ocean environment and properties of the acoustic sources, receivers and waveforms that make up ocean-going acoustic systems of interest to the U.S. Navy. Present day active acoustic system performance models, which contain reverberation models as an essential component, are over twenty ...

Physical Sciences Inc. (PSI) and their academic partner, West Virginia University (WVU), are pleased to propose a uniquely innovative approach to measuring the three-dimensional air wake velocity field behind ship structures and towers. The velocity data is needed to support the validation of CFD models that will ultimately be used to provide sufficient safety margins for ship aircraft operations ...

Current atmospheric diving suits and remotely operated vehicles (ROVs) have end effectors with simply 1 DOF. This rudimentary manipulation results in excessive time spent working a problem underwater, development of task specific tools that can be operated by the pliers or acceptance that a specific job simply can't be accomplished. Vishwa Robotics proposes a teleoperated, anthropomorphic end ...

Green laser sources are important in advanced naval mine detection as this wavelength has good penetration though seawater. Mine detection programs such as the Coastal Battlefield Reconnaissance and Analysis (COBRA) system and the Airborne Laser Mine Detection System (ALMDS) currently use frequency-doubled 1-µm lasers as the laser source. The generation of green laser light via frequency doubling ...
