Low Noise Millimeter Wave LNA Project
nasa-test-0.demo.socrata.com | Last Updated 2015-07-20T05:24:11.000ZThe Phase I effort will result in a low noise MMIC G-Band amplifier the covers the entire 165 to 193GHz frequency range. The amplifier will be designed using a 50nm MHEMT that has already been developed by BAE Systems that enables the state-of-the-art performance to be achieved. The innovative amplifier design will have a gain of 20dB, a noise figure of less than 6dB(~4dB, an input output VSWR of less than 2:1. In addition, the MHEMT has the added advantage of having lower noise power stability and 1/f noise than InP devices. A balanced amplifier is the primary approach while a single ended unit will be investigated for missions that require reduced bandwidths. The MMIC amplifier will be designed to be inserted into a waveguide housing for additional and environmental testing in a Phase II program. At completion of the Phase II program, the amplifier will be capable of being space qualified for NASA missions.

Photonic antenna enhanced middle wave and longwave infrared focal plane array with low noise and high operating temperature Project
nasa-test-0.demo.socrata.com | Last Updated 2015-07-20T05:33:59.000ZPhotodetectors and focal plane arrays (FPAs) covering the middle-wave and longwave infrared (MWIR/LWIR) are of great importance in numerous NASA applications, including earth remote sensing for carbon-based trace gases, Lidar mapping for earth resource locating, and environment and atmosphere monitoring. Existing MWIR/LWIR photodetectors have a low operating temperature of below 77K. The requirement for cryogenic cooling systems adds cost, weight and reliability issues, making it unsuitable for satellite remote sensing applications. This STTR project aims to develop a new plasmonic photonic antenna coupled MWIR/LWIR photodetector and FPA with significantly enhanced performance and a high operating temperature. In Phase I, we developed a preliminary plasmonic photonic antenna enhanced MWIR/LWIR photodetector and demonstrated significant enhancement in photodetectivity and operating temperature. Antenna directivity is also tested and agrees with the simulation. The phase I results not only demonstrated the feasibility of achieving high performance MWIR/LWIR photodetector using the proposed innovation, but also show its promising potentials for high operating temperature FPA development. Motivated by the successful feasibility demonstration and the promising potentials, in this STTR Phase II project, we will develop a prototype of the plasmonic photonic antenna enhanced MWIR/LWIR FPA with a high operating temperature and demonstrate its earth remote sensing capability.

nasa-test-0.demo.socrata.com | Last Updated 2015-07-20T05:27:16.000ZThe proposed innovation is a robust and user-friendly software environment where NASA researchers can customize the latest HHT technologies for the LISA (and LIGO) application. The proposed technology will include the latest discoveries and inventions not available in the state-of-the-art. Its taxonomy includes gravitational sensors and sources, expert systems, portable data analysis tools, software development environments, and software tools for distributed analysis and simulation. The disturbance caused by the passage of a gravitational wave is expected to be very small and will be measured with laser interferometry. The Hilbert-HuangTransform (HHT)and related analysis technologies developed since the original concept has been used successfully in other applications to extract non-linear and transient signal comonents of very small magnitude with respect to the measured signal. The proposed research and development team has participated in the latest cycle of technology development related to the HHT at the theoretical, implementation, and application levels. Not only will the creation of the proposed software contribute to the data analysis of the gravitational wave signals in the laser interferometry measurements (for both LIGO and LISA data), but also in other applications within and outside NASA's mission.

Novel Versatile Intelligent Drug Delivery Project
nasa-test-0.demo.socrata.com | Last Updated 2015-07-20T05:23:14.000ZThis SBIR project will demonstrate and develop a novel micro-pump capable of controlled and selective chemical transport. Phase I will create, characterize, and model a robust and readily fabricated low-power miniaturized pump achieving "forceless" dissolved ion transport compatible with microgravity conditions. The compact technology will be extremely versatile, low-cost, stable, easily tailorable, and readily scaleable to higher fluxes via structure duplication and application in parallel. The device will be physically stable, chemically inert, and pH insensitive while its small dimensions result in lower power consumption and reduced mass. The result will be a more versatile and general pump capable of moving a variety of drugs. Phase I will explore the pump performance, stability, and design optimization using selected ionic compounds as model transport subjects by running designed experiments exploring pump operations as a function of key pump structural and operation variables. This data will determine the controlling variables, their effects on the system performance, and will be utilized with first-principles system physics analysis to develop a pump operation model. This model will allow rapid technology configuration exploration, operation performance refinement, and will provide critical insights into preferred, better optimized, structures to be evaluated during Phase II.

High Performance Negative Feedback Near Infrared Single Photon Counting Detectors & Arrays Project
nasa-test-0.demo.socrata.com | Last Updated 2015-07-20T05:16:13.000ZAmplification Technologies Inc ("ATI") proposes to develop the enabling material and device technology for the design of ultra low noise, high gain and high speed near-infrared single photon counting photodetectors and arrays sensitive in the 1000 nm to 1600 nm spectral region for long range space communication applications, based on the already proven mechanism of internal discrete amplification technology in InGaAs/InP material system. We plan to achieve this by designing the InGaAs/InP internal discrete amplifier photodetector and photodector array device structure by building on the design that gave promising results to prove the concept of internal discrete amplification mechanism in the InP material system. The primary accomplishments from the Phase I effort would be the development of ultra low noise (low jitter), high detection efficiency, very high gain and high speed near-infrared photodetectors and arrays sensitive in the 1000 nm and 1600 nm spectral region. The technology of internal discrete amplification enables the combination of high speed, very high gain and ultra low noise. This is possible because the internal discrete amplification nullifies the effect of impact ionization coefficients and prevents the edge break down, with high detection efficiency and high speed of operation. These photodetectors might also be used in missile seekers, battlefield target identification and recognition systems, and eye-safe LADAR. Potential civilian applications include fiber-optic telecommunications, remote sensing and laser spectroscopy.

Pilot 2006 Environmental Performance Index (EPI)
nasa-test-0.demo.socrata.com | Last Updated 2015-07-19T08:35:45.000ZThe Pilot 2006 Environmental Performance Index (EPI) centers on two broad environmental protection objectives: (1) reducing environmental stresses on human health, and (2) promoting ecosystem vitality and sound natural resource management. Derived from a careful review of the environmental literature, these twin goals mirror the priorities expressed by policymakers. Environmental health and ecosystem vitality are gauged using sixteen indicators tracked in six well-established policy categories: Environmental Health, Air Quality, Water Resources, Productive Natural Resources, Biodiversity and Habitat, and Sustainable Energy. The Pilot 2006 EPI utilizes a proximity-to-target methodology focused on a core set of environmental outcomes linked to policy goals for which every government should be held accountable. By identifying specific targets and measuring how close each country comes to them, the EPI provides a factual foundation for policy analysis and a context for evaluating performance. Issue-by-issue and aggregate rankings facilitate cross-country comparisons both globally and within relevant peer groups. The EPI is the result of collaboration among the Yale Center for Environmental Law and Policy (YCELP), Columbia University Center for International Earth Science Information Network (CIESIN), World Economic Forum (WEF), and the Joint Research Centre (JRC), European Commission.
