This Small Business Technology Transfer program will develop a spectroscopic polarimeter-on-a-chip using novel plasmonic resonant cavities sensitive to linear polarization over a narrow wavelength range. Spectral selection will be possible through geometric scaling, with this work concentrating on the visible to near infrared wavelength band. Dielectric gratings with subwavelength period will act ...

Carbon fibers are widely used in a variety of applications including aerospace, military and automotive. These applications are limited by the trade-offs that must be made between structural and conductive properties. A new area of interest is the nanotailoring of fibers with carbon nanotubes (CNT) to produce a high strength, high modulus light-weight carbon fiber that is thermally and/or electri ...

Nano-photonics, defined by the fusion of nano-technology and photonics, is an emerging frontier providing challenges for fundamental research and opportunities for new engineering technologies. Due to the rapid advancement of functional polymers exploiting Pockel effect from large hyperpolarizability chromophores, nano-photononics on electro-optic (E-O) polymers is anticipated to play a significan ...

ABSTRACT: Simultaneous sensing of light of multiple wavelengths can greatly enhance survivability, sustainability, and versatility by enabling unmanned reconnaissance and intelligent surveillance for both DoD and homeland security. The objective of this STTR Phase II proposal is to continue and complete the development of a new type of multi-color/band nanomembrane imaging sensor array system, ba ...

ABSTRACT: The objective of this STTR Phase II project is to demonstrate that resonant infrared matrix-assisted pulsed laser evaporation (RIR-MAPLE) is a commercially-viable technology for the deposition of hybrid organic/inorganic polymeric, gradient refractive index, anti-reflection (GRIN-ARTM) coatings on both rigid and flexible substrates. Description of Effort: Based on the feasibility rese ...

ABSTRACT: There are a growing number of military (and civilian) applications for unmanned aircraft. To extend their mission capabilities, unmanned aircraft can incorporate solar panels onto their structure to generate electrical energy from the sun. Solar cell efficiency is inversely proportional to the cell's operating temperature. Therefore, thermal management of solar modules is import ...

The problem addressed in this effort is to automatically learn historical ephemeris space catalog time, position, and velocity entity track update error uncertainties (i.e., without track error covariances) and to automatically (e.g., without expert event labeling) produce: – unmodeled non-gravitational space catalog update flags – abnormal unmodeled catalog update flags with abnorma ...

ABSTRACT: We propose to develop an assured information sharing framework for cloud-based systems that leverages our ongoing work in the areas of policy-based usage management and semantic interoperability. The development of this framework will involve the creation of a novel approach to information sharing that treats security as a commodity that can be dynamically provisioned within the cloud, ...

ABSTRACT: This proposal sets out a plan to continue the method development for selective chemical oxidization of one amine of a polyamino, multi-heterocyclic class of energetic materials. The approach is based on screening one substrate (DAAzF) with many different oxidants under a variety of conditions including microwave heating to find those conditions where one amine group has been oxidized t ...

ABSTRACT: RNET and The Ohio State University propose to use algorithmic modifications and multi-level parallelization techniques and tools to improve the scalability of the aero-line/aero-elastic coupled CFD/CSD codes relevant to the DoD/AF (e.g., CREATE/Kestrel). The optimizations will address inter-node and intra-node parallelization to better target emerging compute architectures (e.g., multi ...
