Abstract:In this proposal, we outline an approach for performing a complete electromagnetic analysis of electrical circuits in a fraction of the time that is currently possible. As clock rates increase, the need for such analysis grows. Current tools are inadequate to handle this burden. The computational… more
Abstract:The rapid expansion in the electronics industry has given rise to what has become known as Moore's law. At its core, lies advances in lithography that enable the miniaturization of features patterned on semiconductor substrates. As the minimum feature patterned on modern integrated circuits… more
Abstract:Pressure ulcers are a serious medical problem with annual treatment costs over $1 billion dollars. While the exact etiology involves a complex combination of factors, it is generally accepted that prolonged pressure to soft tissues results in discrete areas of acute ischemia. If the pressure is not… more

Abstract:A number of military situations require individual soldiers and pilots to instantaneously respond to complex visual scenes and make rapid decisions regarding potential threats. Text and graphics overlaid on the scene provide a means to aid the soldier in the decision making process. Helmet mounted… more
Abstract:… long proposed, their use on thechip-scale has been limited due the incompatibility of optical device materials and disparate integration scales, in comparison to electronic device materials and scales. Thus, to overcome this limitation we will demonstrate a photonic crystal… more
Abstract:… more rigorouselectromagnetic analysis is required. Thus, new computer aided design (CAD) tools are needed that integrate the rigorous physical models and fabrication processes into a single desktop environment. To solve this very challenging problem we propose toapply EM… more
Abstract:In this effort we propose to develop an integrated analysis and design environment for the rigorous electromagnetic analysis and design of complex shipboard RF interactions for low frequencies (30MHz-2GHz). This integrated environment will include theability to predict the scattering and EMI… more
Abstract:… of near-field methods including tapered fibers, solid immersion lenses, and mode index waveguide lenses. Based on advances in semiconductor processing techniques, a new class of optical devices based on submicron periodic structures has emerged and is referred to photonic… more
Abstract:DESCRIPTION (provided by applicant): The ability to accurately measure in vivo tendon forces would have a broad impact on assistive technologies as well as our scientific understanding of the human neuromuscular control system. Myoelectric prosthetics and functional electrical stimulation devices… more
Abstract:… continued to pursue small-scale fabrication and have advanced to thesubmircon or nano regime. At these dimensions, where feature sizes are less than the wavelength of light, it is possible to produce optical materials and devices that allow for unique photonic control and… more
Abstract:DESCRIPTION: Recently, New Photonics LLC (NP) demonstrated that newly developed
blue Light Emitting Diodes (LEDs) used in continuous mode can provide up to 4
mm depth of cure in Dental composite resin in about 2 minutes of exposure.
Despite its many advantages, the commercial… more
Abstract:In this effort we proposed to develop an integrated software environment for the rigorous electromagnetic analysis and design of diffractive optical elements (DOEs). To this end, we will develop a user-friendly graphical user interface (GUI) specificallygeared towards DOEs; we will refine, expand… more
Abstract:… time.In the Phase II effort we will continue our development of the hardware implementation of the FDTD method and expand its application to two- and three-dimensions. In addition, the CAD tool will be expanded to include the ability to analyze and designadditional photonic… more
Abstract:The Phase I Project will develop a comprehensive model to evaluate and optimize state-of-the-art light-emitting diodes for optical memories, optical computing, and fiber or free-space photonic interconnects. The innovation is the development of resonant optical cavity LEDs and a… more
Abstract:… AND REDUCING BACK SURFACE RECOMBINATION. A HETEROJUNCTION CONTACT FORMED AT THE SILICONGAP INTERFACE THROUGH VIAS IN THE OXIDE WILL MINIMIZE BACK OHMIC CONTACT LOSSES. AND FINALLY, THE WIDE BANDGAP, INFRARED TRANSPARENT GAP SUBSTRATE WILL ALLOW LONG WAVELENGTH PHOTONS TO… 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.
