Ultra-high performance multi-function RF electronics are required by the United States Department of Defense to enable next generation radar and sensor networks in response to an increasingly diverse array of threats to our military and our homeland. An elegant potential solution is that of gallium nitride (GaN) RF electronics, which has shown great promise on currently available yet foreign subs ...

This Phase II effort demonstrates the feasibility of integrating a chemically powered or “active” infrared (IR) treatment into an inflatable device and then perform three experimental excursions with the hardware: 1) achieve a tunable IR signature by cooling the surface; 2) achieve tunable IR emissions combined with a predetermined and fixed radar cross section (RCS); and 3) achieve both varia ...

Bearing failure in satellite applications is related to lubricant starvation rather than fatigue, and health monitoring systems for these applications must be able to observe subtle changes related to lubrication state. Phase I included an experimental study to identify candidate monitoring approaches, and the data collected confirmed that cage motion characteristics and instability are highly sen ...
