Abstract:This Small Business Innovation Research (SBIR) Phase I project aims to provide a novel technique for the micro-mark data matrix and portable machine reading of micro-codes on very small devices, as current marking methods are not applicable for such devices such as those used in craniomaxiofacial… more
Abstract:Many of the safety incidents that occur with lithium-ion batteries are due to the carbon anode currently in use. Incidents can occur that include overcharging in the system, which causes lithium metal to plate out of the cell and passivation at the surfaces of the electrodes in the cell, which can… more
Abstract:With the United States dependence on foreign oil imports, new renewable sources of fuel compatible with combustion engines must be found. A source of this new biofuel could be the jojoba plant which is native to the desert Southwest. This is a plant which grows on non-arable desert lands which do… more
Abstract:Several hundred beam lines are used around the world at today¿s third-generation synchrotron facilities. These facilities must deal with monochromator-based performance problems due to high heat load. Many have resorted to the use of costly, complicated, high maintenance cryogenic cooling of… more
Abstract:As NASA prepares for the Constellation Space Missions and Extra-Vehicular Activity (EVA) on the moon by 2018, astronauts will be required to spend more time exposed to the hazards of EVA operations. Providing reliable communications is imperative during current EMU/ISS operations as well as future… more
Abstract:Physical insights provided by the Characteristic Mode (CM) theory are utilized to optimize HF, VHF, and UHF antennas onboard small low-cost autonomous scouting/surveillance UAVs. Increasing demand for real-time high data rate communication links between mobile or short-term stationary network nodes… more
Abstract:Much effort has been devoted in recent years to develop compact broadband antennas to address antenna congestion on small aerial platforms (including small Unmanned Airborne Vehicles) to address the explosive growth of communication and connectivity needs. Over the past decade, Applied EM has also… more
Abstract:Small antennas are required to support surveillance sensors, communication links, navigation systems, command and control systems, and precision strike capabilities on Unmanned Combat Aerial Vehicle (UCAV). Research advancements in metamaterials show promise in the design of high efficiency small… more
Abstract:Currently available communications antennas for aircraft have several problems. Blade antennas are inherently resonant structures that are difficult to extend to wider bandwidths, they impact the flight characteristics of faster aircraft, and they may present an ice accumulation problem on some… more
Abstract:US Department of Defense is heavily dependent on the Global Positioning System (GPS) for geolocation, navigation, timekeeping and other military operations. Multipath due to the structure (platform on which the GPS receiver is mounted) scattering can degrade the accuracy of GPS measurements (code… more
Abstract:The goal of this effort is to provide electromagnetic scattering tools (radar cross section/RCS codes) for small boats in littoral and deep ocean environments. This goal is within the larger scope of developing electromagnetic (EM) modeling and simulation (EMMS) tools for large scale simulations as… more
Abstract:Body wearable antennas are needed in the context of Tactical Network Communications for the Land Warrior/Ground Soldier System ensembles. Specific bands of interest are 225-1000 MHz and 1350-2700 MHz. These frequency bands are particularly vulnerable to signal cancellations due to multipath.… more
Abstract:Ubiquitous needs for Global Positioning System (GPS) systems implies a requirement for smaller GPS antennas and arrays that can be adapted in all sorts of military and commercial platforms from missiles to small UAVs and even for hand-held applications. Current anti-Jam GPS antennas are… more
Abstract:Currently, there are two types of antenna configurations which are used with GPS receivers, fixed reception pattern antenna (FRPA) and controlled reception pattern antenna (CRPA). FRPA is a single element antenna and can not use angle of arrival as a discriminator to suppress interfering or jamming… more
Abstract:Lasers based upon rod architectures offer a simple and rugged method for amplifying an Ultra-Short Pulse (USP) duration laser pulse at moderate powers. When paired with a chirped pulse amplifier (CPA) chain, greater system flexibility and capabilities are realized. This proposal provides solutions… more
Abstract:The goal of the Phase I SBIR effort is to characterize and specify the application of the relevant parts of the MARTE profile into a class and component library including resources, networks, busses and other constrained-use artifacts (e.g. Devices, data tables, system locks, etc) so that a complete… 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.
