Abstract:We propose a two-layer anti-reflective coating (ARC) that will have omni-directional properties. This coating will guide the light that is incident from oblique angles and orient it to become perpendicular to the solar cell surface. The top-most part of the coating will have a graded index of… more
Abstract:We will continue developing a plasmonic metamaterial with strong absorption within a narrow band that is dynamically tunable over the 8-10 micron range. A metamaterial consisting of one or more bi-layers of thin metal and dielectric films will trap, concentrate and absorb a narrow frequency band… more
Abstract:This project will develop plasmonic films that perform the dual functions of optical filtering and electrical conduction for solar-blind ultraviolet radiation (UV) detectors. Two types of plasmonic structures will be investigated, namely nano-hole arrays in an aluminum film atop UV radiation… more
Abstract:We propose a meta-surface consisting of a periodic array of metal-like patches that will allow focusing and steering a radiation beam in the millimeter frequency range. The direction of the beam will be controlled by controlling the phase change acquired by the beam as it is transmitted through this… more
Abstract:We propose further developing very large LED arrays for IRSP applications. Our Phase I effort has demonstrated the feasibility of LED arrays of up to 2048x2048 pixels. In this effort, we seek to further increase the resolution of these arrays by developing technologies that will permit smaller… more
Abstract:We propose to develop and commercialize a new class of aperiodic multilayer coating that is designed to provide high normal-incidence reflectance over a wide spectral band-pass in the extreme ultraviolet (EUV) region, specifically from 9 to 14 nm. A broad-band reflective coating working at these… more
Abstract:This SBIR develops new innovative clustering and de-interleaving algorithms, leverages and refines existing algorithms and software, and integrates them within an open architecture framework to address a wide variety of radar signal classes for a submarine EW/ISR application. The proposed effort… more
Abstract:This SBIR develops technologies to automate the creation of Electronic Warfare (EW) emitter libraries to correctly identify threat (and other) signals of interest. In this effort RAS will show how to automate the use of the national databases to extract data and manipulate it into a form suitable… more
Abstract:This SBIR develops clustering and de-interleaving algorithms to process non-contiguous clusters of pulses, collected from acquisition scanning receivers periodically sampling (spectrally, spatially, and temporally) subsets of the signal environment, to better perform Emitter Identification (EID).… more
Abstract:ABSTRACT: This SBIR develops and evaluates innovative Specific Emitter Feature (SEF) techniques using multiple algorithms for"Operational Specific Emitter Identification (SEI)", aka Specific Emitter Tracking (SET) or Combat Identification (CID), to provide a common functionality for… more
Abstract:In Phase II, based on the Phase I success, we propose to research further enabling optimizations for a wider range of sensor applications than in Phase I. We will also implement the key optimizations to SAR found in Phase I within the SANE high-productivity array language and automatic… more
Abstract:Very low cost (pico and pocket) projectors provide an opportunity to achieve significant cost reduction for immersive visual display systems currently used in training applications. Traditional methods to achieve very large fields of view utilize expensive, high resolution display devices. The cost… more
Abstract:Integrally bladed rotors (IBR), also called blisks, are becoming increasingly common in the compressor and fan sections of modern turbine engines. The integration of the blades and disks into a single part has the advantages of reduced part count, reduced weight, increased reliability, and increased… more
Abstract:The DOE supports development of technologies essential to experiments in nuclear physics. The channel count of modern nuclear physics experiments has risen into thousands. There is need for cost effective, high density data acquisition (DAQ) systems with many thousands of channels. Our approach… more
Abstract:ABSTRACT: The objective of this proposal is to develop a high torque, compact and reliable rotary electromechanical (EMA) actuator for next-generation thin-wing military aircraft flight control. This topic seeks to develop advanced rotary EMA technologies for primary flight control actuation… more
Abstract:DESCRIPTION (provided by applicant): We propose to develop a broadly neutralizing, possibly universal influenza vaccine based on virus-like particles (VLPs) displaying remodeled HA molecules which present otherwise cryptic epitopes. These remodeled HAs will be expressed in forms lacking the dominant… more
Abstract:DESCRIPTION (provided by applicant): Genital tract infection with Neisseria gonorrhoeae (gonorrhea) does not induce a state of specific protective immunity and can be acquired repeatedly. Despite public health measures, the disease persists at an unacceptably high frequency; there is no vaccine… more

Develop a prototype of a rapid portable instrument for detecting and measuring the amount of Human Immunodeficiency Viruses (HIV's) in samples of patient… more
Abstract:DESCRIPTION (provided by applicant): Striking changes in dietary patterns and decreases in physical activity have driven the prevalence of obesity among American children to epidemic proportions; low-income and ethnic minority families are especially vulnerable to the socio-economic barriers that… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
