AlInGaN-based heterostructures have demonstrated unmatched versatility in optical and electronic applications. In particular, AlGaN/GaN high electron mobility transistors (HEMTs) are the leading candidates for realizing ultra-high frequency, low-noiseand high-power amplifiers. The addition of indium to the composition of these HEMTs is expected to dramatically improve their performance. We prop ...

Fiber optical transmission is increasingly applied to computer network, secure telecommunication systems, military aircraft, and even in missile guidance systems. 1300 nm vertical cavity surface-emitting lasers (VCSEL) are becoming a prefered technologyfor transceivers in short- and medium-haul, enterprise and metro data network. There is significant interest in using diluted nitride GaInNAs as ac ...

Earths outer radiation belt, which consists of electrons with hundreds of keV to MeV energies, is a highly dynamic and driven environment.The large variations in electron flux, if unaccounted for, can cause satellites that travel through this complex region to experience anomalous behavior ranging from temporary satellite outages due to electrostatic discharge events in system electronics to poten ...

Military systems operate in complex, adversarial environments where their initial planned operations are often overcome by events, but soldiers use those systems in creative ways to achieve their mission objectives. For example, complex ground robotic systems that were initially deployed for surveillance and explosive ordinance disposal have instead been used as decoys, ammunition carriers, and ot ...

SIFT proposes Network Enforcement Using TRansactONs (NEUTRON) a dynamic fine-grained network enforcement policy design that captures network dependencies.NEUTRON closes the knowledge gap between mission needs and observed network traffic to increase mission network awareness. Then using that knowledge develops a revolutionary security enforcement policy based on network transactions.It reduces the ...
