This proposal addresses the development of nanostructured dielectric materials with a nonlinear parametric response, designed to be integrated into a high power capacitor system. Recent developments in nanodielectrics utilizing metal-insulator transition and plasmon based phenomena have resulted in non linear capacitor dielectrics with ultra high dielectric constants but relatively low breakdown ...

A consistent time-accurate Hybrid gaskinetic Bhatnagar-Gross-Krook (BGK) method (H-BGK), valid in the full Knudsen number (Kn) range, is proposed using Cartesian grid as a 3D tool to handle hypersonic aerothermodynamics from continuum to thermochemical nonequilibrium and ionized/plasma flows.  H-BGK method is to provide automated sub-domain solutions by direct BGK method and the gaskinetic BGK me ...

New methods and technology to rapidly characterize UHTC creep are necessary to fully understand and exploit their high temperature properties for hypersonic vehicles and rocket nozzles. Recently, the University of Michigan has developed a rapid, table top apparatus for characterizing the oxidation behavior of UHTC’s. A team comprised of Advanced Ceramics Manufacturing (ACM) and the University ...

The primary objective of the proposed research program is to realize a miniature, high-speed, low voltage hybrid photonic crystal waveguide modulator based on state-of-the-art electro-optic polymers with electro-optic coefficients on the order of 200pm/V as well as innovative poling, leading edge silicon photonics and EO polymer infiltration techniques.  Phase I work has demonstrated the viabilit ...

The overall goal of this proposal is to develop a large area updateable 3D color display using unique photorefractive (PR) polymers with fast writing times (ms), long persistence (hours) and rapid erasure (seconds). As published in a recent Nature paper, the University of Arizona team has demonstrated for the first time that photorefractive polymers may be used for 3D displays with an image persi ...

As the power demands of airborne sensor platforms increase there is a growing need for improved capacitor technologies for compact energy storage.  While progress has been made on electrolytic supercapacitors as well as nanocomposite composites, an ultrahigh dielectric strength capacitor with high dielectric constant and compatibility with a broad range of associated materials technologies is sti ...

This SBIR Phase I project proposes to develop an accurate viscous CFD algorithm which can include various small gaps between both static and moving components into the analysis. It is not an easy task to model those small gaps in the current CFD codes due to the geometric proximity, especially for moving components. However, those small gaps may have a significant impact on the aerodynamic, aeroel ...

The ability to measure and characterize critical circuit parameters is a necessary requirement to developing reliable microelectronics for military applications. An industry-first capability is provided: a set of radiation-hardened by design (RHBD) test structures to allow design engineers to measure and characterize these critical parameters both before and after irradiation. Upon completion, the ...

Expert analysis tools that rapidly and accurately evaluate the reliability of electronics modules, such as printed circuit board assemblies (PCBA) for component health, performance and situational self awareness, are critically important to mission effectiveness of DoD systems. To accomplish this, the interactions between electronic components need to be predicted and monitored within a comprehens ...
