ABSTRACT: Carbon nanotubes (CNTs) have great potential for high performance RF applications. Theoretical study has shown that the electrical current in a CFET is intrinsically linear. Today, linearity is the underlying limitation in increasing the data transport densities of wireless networks. The complex modulation protocols used to achieve higher data rates requires linear amplifiers. Increasing ...

ABSTRACT: In this project, we propose to develop the baseline process to form low source-drain contact resistance to the CNTs. This includes finding the right metal stack and annealing recipe to form good ohmic contact to the CNTs. The goal is to achieve a resistance less than 25 k at per nanotube contact. To reach such goal, we will leverage the interfacial dipole alignment of conjugated polyelec ...

ABSTRACT: Speech recognition technology is in wide use today and has been successfully integrated in a number of applications. Most of these applications require a microphone located near the talker. However, when a distant microphone is used where the speaker is at some distance from the microphone as in a hands-free communication, or in a meeting room, there is a major problem with the captured ...

ABSTRACT: Active control of the shock system in a scramjet engine isolator opens possibilities for enhanced engine performance and reduced engine weight by eliminating excess isolator design margin. A successful system will allow for maximum performance from a given engine configuration and will deliver range and efficiency that exceeds those possible using passive unstart control. Our approach is ...

ABSTRACT: Exquadrum, Inc. proposes to develop an innovative multi-mode power generation system for hypersonic flight vehicles. This system produces the required power output that the flight vehicle demands, independent of the flight characteristics at the time. However, this system will work in conjunction with the propulsion system to augment the power generation capabilities. This is accomplishe ...

ABSTRACT: An unseeded measurement technique is proposed for simultaneous spatially-resolved measurements of density, temperature, and velocity in hypersonic wind tunnel flows with the future potential for time-resolved measurement capability. A variant of filtered Rayleigh scattering (FRS) will be developed that takes advantage of unique monotonic relationships between molecular vapor cell filter ...

ABSTRACT: Hypersonic vehicles will require structures that can withstand highly transient flows and complex loadings throughout the flight trajectory. Shock boundary-layer interaction can excite panels locally and lead to structural failures. Non-contacting measurement technologies are needed to characterize the effect of flow transients (due to pressure and temperature fluctuations) on the struct ...

ABSTRACT: MZA partnered with the University of Notre Dame proposes to extend MZAs WaveTrain wave-optics sensor simulation framework to model EO/IR sensors operating on hypersonic aircraft. Following the methods we have developed for aero-optical imaging through subsonic, transonic, and supersonic flows, existing WaveTrain libraries will be expanded to include hypersonic flow, shocks, thermal effec ...

ABSTRACT: A platform (PHA-fuse) for the stabilization of diagnostic and therapeutic reagents will be established based upon the polymer, polyhydroxyalkanoate (PHA). Fusions of a target molecule to PHA synthase, the enzyme responsible for PHA synthesis, will be constructed and used to catalyze the synthesis of PHA granules. These PHA granules will help stabilize the fused target molecules and elimi ...

Experimental data from a number of DoD supported research programs have indicated that electrical systems capable of producing highly repetitive bursts of high voltage, fast risetime pulses are a critical enabling technology for applications tied to nonequilibrium physical processes, such as combustion, boundary layer flow, and the generation of high power EM waves. Recognizing the important role ...
