Existing physics-based device simulation tools are prohibitively expensive computationally, and therefore ill-suited for parametric analysis and design optimization of photonic integrated circuits (PIC). The proposed effort aims to develop and demonstrate an innovative, easy-to-use simulation tool for accurate, fast circuit/system analysis of PICs. The salient aspects of the proposed solution are: ...

It is increasingly difficult for companies to enter the spare parts business. To produce a spare part, the manufacturer must recreate the form, fit and function of the original part, which can be especially difficult with high strength forged metal parts. There are processes available to the forging engineer to recreate the geometry and material chemistry of original part; however, getting the par ...

The potential for solid fuel ramjets (SFRJ) has been demonstrated over the last 40 years. SRFJ"s have significantly higher impulse than rockets (Isp>1200 sec) making them a competitive solution for long range applications such as missiles, missile interceptors, high speed transport and space vehicle stages. Increasing the regression rate and the energy density of the fuel further improves the adva ...

We propose to develop a space based radiation hardened GPS transmit antenna capable of forming spot beams to enhance the GPS signal on the ground by greater than 5 dB. It is expected that our transverse compound hybrid antenna will provide as much as 30 dB gain over a hemispherical antenna allowing enhanced signals over specific areas as large as 500 km. A tradeoff between spot size and signal g ...

Oceanit proposes to develop an ASM system using a novel sigan processing technique. The proposed technique enables agile detection, location and identification of threat signals. The proposed sampling technique reduces the amount of data without impairing radar capabilities, thus enabling persistent intelligence, surveillance and reconnaissance (PISR).

Building on success in Phase I, this proposal focuses on the theoretical analysis, system level optimization, manufacturability, TRL progression and prototypic demonstration of IntraMicron's Enhanced Battery Pack (IEBP). IEBP facilitates rapid cooling of

A novel signal processing technique, totally comprised in software, was demonstrated in Phase I using a MATLAB based laboratory simulation and target/clutter data provided by the Government. Although Government supplied data was in a form suitable only for partial processing by the new technique, nevertheless, Signal to Clutter Ratio improvements of 7-13 dB were demonstrated depending upon the par ...

WCDMA payloads on fast-moving platforms, such as on satellites in Molniya orbits or on UAVs, will likely be added to the battlefield to assure the warfighter of reliable, ubiquitous communications. The algorithms for handoffs, timing, and Doppler correction suitable for near-Geosynchronous platforms will not be suitable for these fast movers. Power control algorithms may or may not be suitable. Th ...

ABSTRACT: The overall goal of the proposed effort is to develop and demonstrate a general-purpose, fast, and reliable management and learning software tool for analyzing massive data sets generated by dynamic multi-disciplinary simulation. In Phase I, key technology elements were developed and proof-of-principle was successfully demonstrated. Data management software encapsulating salient feature ...

Modern combustion systems such as liquid rocket engines and gas turbines are characterized by high operating pressures and temperatures due to increased power-density. Thermal radiation has significant impact on both heat fluxes at the wall and on physical phenomena controlling the combustion process at these conditions. Coupling between radiation, turbulence and chemistry can have a large effect ...
