Award Data

Passive microwave sensors aboard satellites provide valuable information regarding weather conditions by measuring atmospheric attenuation over a broad range of frequencies from 0-200 GHz. Additional ground-based sensors are desirable to provide complementary upward looking measurements that can be used to refine existing attenuation models. Operating over such a large bandwidth, however, places ...

In the area of supply chain integrity improvement, the US defense and intelligence sectors anticipate multiple uses for the forensic capability to characterize an electronic component for the purpose of identifying the semiconductor fabrication facility w

This SBIR project proposes to develop a gas-kinetic CFD solver for separated turbulent flow simulation. After successfully developing prototype two-dimensional gas-kinetic BGK-NS/Burnett solvers and demonstrating the benefits of using higher-order hydrodynamic equations for separated turbulent flow simulation in Phase I, the technical objective of Phase II work will be to fully develop and validat ...

Based on promising results obtained under our Phase 1 SBIR contract, nLIGHT wishes to proceed with a Phase 2 program. In the proposed program, nLIGHT will continue the development of high power, single-lateral-mode tapered diode lasers. nLIGHT has identified fundamental limitations to the operation of tapered diode lasers and proposes novel design and fabrication process improvements which direc ...

Typically, the electro-optical Mach-Zehnder interferometric intensity modulator is the key optical component that determines the ultimate performance of an externally-modulated high-performance analog RF fiber-optic link. Intrinsically, the device has a symmetric structure and has a transmission peak at zero bias. In order to operate at the maximum linearity quadrature point, the optical symmetr ...

In this Phase 2 program, nLight intends to demonstrate high-reliability / high-efficiency 808-nm broad area diode lasers. The root-cause of the failure modes of diode lasers investigated under Phase 1 will be addressed in this program. Collaborative work on built-in filament control by etching holes will continue in this program. Prototype designs first demonstrated by focused ion beam processi ...

During the program baseline, LCI will develop an eyesafe, large array RT3D camera system that generates both 3D and 2D grayscale imagery in real-time that can be mounted on the iRobot PackBot. The 3D and 2D grayscale imagery can be fused in software to display both range and albedo information for each pixel in the 3D image, a display that will provide better scene understanding. During the option ...

This program will entail making further refinements to a rapidly polymerizable resin which was shown during the Phase I Program to induce corrosion and ductility loss within treated steel rifle barrels. Besides optimizing the formulations, efforts will also be directed during this Phase II program towards devising suitable equipment for efficiently dispensing this resin into rifles using truck, b ...

AN EXPERIMENTAL INVESTIGATION OF INNOVATIVE FLAMEHOLDER DESIGNS TO ENHANCE MIXING IN A SUPERSONIC COMBUSTION RAMJET (SCRAMJET) ENGINE IS PROPOSED. IN A SCRAMJET ENGINE OPERATING AT HYPERSONIC FLIGHT SPEEDS,THE SHORTER RESIDENCE TIME AND DECREASED MIXING RATE CAUSE DETERIORATION IN THE COMBUSTION EFFICIENCY AS COMPARED WITH LOWER SPEEDS. TWO CONFIGURATIONS RECENTLY DEVELOPED TO PROMOTE RAPID MIXING ...

The work proposed here consists of design, fabrication, packaging, and characterization of latching magnetic RF MEMS switches operational from dc through 40GHz. The active switching component of the device is a movable ferromagnetic cantilever thatelectrically shunts a gap in an on-chip transmission line (CPW and/or microstrip) to turn the switch ON and opens the gap to turn the switch OFF. Packag ...
