Explosions and high-velocity impacts can create strain rates on the order of 105 to 107 s-1. To simulate these events, first-principles codes require material models that are valid at these loading rates. Currently, the amount of test data, material models and material constants for this strain rate range is extremely limited, and an innovative and cost-effective laboratory test procedure is neede ...

Nanohmics proposes to develop a hyperspectral imager for aft-looking sensing of phenomenology associated with target vehicles.The payload is designed to operate with existing components and has no moving parts.The high spectral resolution will provide feedback for signature models and the spatial resolution will allow the spectral signatures to be associated with specific phenomena.Approved for Pu ...

HIGH-DENSITY ENERGY STORAGE AND FAST DISCHARGE WILL BE CRITICAL IN A VARIETY OF HIGH POWER AEROSPACE APPLICATIONS. CAPACITORS ARE IDEAL FOR THESE PURPOSES, AS WELL AS FOR POWER CONDITIONING AND FILTERING. UNFORTUNATELY, BULK POWDER-BASED DIELECTRICS USED IN CAPACITORS HAVE SEVERE LIMITATIONS, ESPECIALLY THE HIGH NUMBER OF SHORT-INDUCING DEFECTS CAUSED BY POOR CONTROL OF MATERIAL PROPERTIES IN CERA ...

The development of a process to produce semi-insulating (SI) silicon carbide (SiC) boules with improved yields will significantly reduce the cost of wafers and thus accelerate the rapid commercialization of SI SiC for microwave and RF system applications.The objective of this Phase II project is to improve and perfect the process development of a radically new approach for the synthesis of high pu ...

We proposed a simple wafer scale method to leap frog current CMOS technology. The slow-down in CMOS scaling is limited by technology difficulties and by economics. In tooling up for .13-micron technology, the jump from .18-micron is costing $10 billionis equipment alone, plus accompanying expenses of redesign and module formulation. The net effect of this massive capital investment is to replac ...

Kigre's Phase I fiber amplifier development effort demonstrated 10dB of internal gain at 1.54um from 2.2 cm long section of MM-2 erbium ytterbium phosphate fiber amplifier pumped at 980nm. 26dB of gain was also produced from a 8.8com long section of thissame fiber pumped at 1480nm. Mode field image testing of a fiber show this MM-2 fiber to be perfect 1.54um single mode containment match to stan ...

An innovative discharge geometry for a very compact, area cooled, high average power CO2 laser employing a two mirror, waveguide-stable optical cavity is proposed. The specific Phase I result sought is the generation of an average CO2 output power of 1 W/cm2 of wall cooling area in a geometry that has a total cooling area of 140 cm2. A lightweight CO2 amplifier version of a future Phase II devic ...

In this proposed Phase II program we will develop board-level optical waveguides to alleviate the ever-tightening electrical interconnection bottleneck. VLSI provides fast intrinsic signal speeds but these speeds cannot be supported by electricalinterconnects between other chips on the same board. Conversion to optical interconnects at the intra-board level can overcome these limits. The pract ...

Conventional wave division (de)multiplexers (WD(DM)Ms) fail to provide a universal design enabling the coverage of the large dynamic range of wavelength separations which vary from sub-nm to 30 nm. The packaging designs affiliated with such WD(D)Ms alsomake the systems vulnerable in harsh environments. In this program, Radiant Research, Inc. (RRI), in collaboration with the University of Texas a ...

Glass is an attractive material for microelectronic packaging because it is hermetically sealing, has a low coefficient of thermal expansion, and is compatible with d.c. circuits. Unfortunately, the working temperature of glass is too high for this application. Low-temperature processing of a sol-gel derived, aluminosilicate material for hermetic seals is proposed for electronic packaging. This ...
