Freedom Photonics is proposing to develop a novel modulator concept. The overall objective of this program is to develop a novel compound-semiconductor electro-optic modulator that simultaneously exhibits 100-GHz operation, optical/microwave velocity matc

CONCUR develops a computational framework for assessing and characterizing urban environments stability or fragility in response to volatility and stress, identifying specific weaknesses as well as key tipping points which could lead to rapid systemic failure. CONCUR explicitly models urban environments as emergent complex systems, focusing attention on the critical triggers that could lead to rap ...

The objective of this proposal is to examine the feasibility of defining and measuring key dimensions of an urban system to include its essential functions and networks, and whether they can be modelled in a computational framework for assessing robustness and resilience of DUTs (and their tipping points) under conditions of volatility and stress. This proposal will conduct a comprehensive review ...

Additive manufacturing (AM) is a very promising technique for rapid, low-cost production of aircraft parts directly from a CAD file. AM is especially appealing for complex parts that would be costly or impossible to fabricate by machining or casting. At the current time there are no reliable, cost-effective techniques to qualify the finished parts. Several government studies have noted this gap an ...

We propose to develop a high-resolution soft x-ray nanoscope based on Fourier Transform Holography which has the very important advantage for real time visualization: 3D images are nearly instantaneously retrieved with a simple 2D Fast Fourier Transform operation. The table-top soft x-ray nanoscope will use for illumination a compact high average power soft x-ray laser that generates high e ...

It has long been known that analog computers can be faster and more power efficient than digital processors by many orders of magnitude. Until the 1970s analog computers were the dominant controllers in most industrial and military applications. Even today digital processors are still slower and more power consumptive than analog, but offer much more flexibility (programmability) and precision. ...

The modern warfighter faces the constant threat of endemic infections, multi-drug resistant bacteria and Biological Warfare Agents. In order to provide accurate front-line treatment that will curtail the overuse of antibiotics, a rapid and robust molecula

ABSTRACT: In this project, we propose to develop the baseline process to form low source-drain contact resistance to the CNTs. This includes finding the right metal stack and annealing recipe to form good ohmic contact to the CNTs. The goal is to achieve a resistance less than 25 k at per nanotube contact. To reach such goal, we will leverage the interfacial dipole alignment of conjugated polyelec ...

ABSTRACT: The hydrocarbon-fueled scramjet is capable of providing hypersonic air-breathing propulsion for high-speed applications. The effective operation of high-speed air-breathing engines (ram- and scram-jets) over a wide range of flow parameters (velocity and altitude) is one of the most technically difficult challenges in the design of hypersonic vehicles. The most promising approach to overc ...
