Future multiband communications systems demand frequency agile filters. While such devices are available at millimeter wave, they suffer from large size and high cost, among others. For this STTR Phase II effort, nGimat, working with Georgia Tech, will develop a miniaturized, low-loss, tunable Ka-band bandpass filter using its low-cost tunable thin film technology. In Phase I, nGimat has succes ...

Micro Air Vehicles (MAVs) employing flapping wings are increasingly gaining attention due to their potential ability to hover in a controlled manner. There has been a growing interest in flapping wings as an unconventional means of integrating lift, propulsion and control. The overall proposed effort will be aimed at building a fundamental knowledge base for the unsteady aerodynamics of flapping ...

This STTR phase II proposal addresses AFOSR's task to: "Develop seamless, easy to use, efficient code to calculate electronic wave functions and potential energy surfaces of molecules and predict kinetic rate constants for reactions a priori." This is a long-unsolved problem, fundamental to chemistry, where quantum chemical methods must be extremely accurate to yield reliable rate constants. Yet u ...

The conceptual design of a novel, hypersonic electromagnetic launch system has been developed. Phase-1 assumed a 100-kg projectile leaving the launcher at 7,000 m/sec. The projectile is propelled and levitated by electromagnetic forces inside a tube filled with low pressure helium. A controlled acceleration profile, fully adjustable to the requirements of various missions, is used to reach 5000 ge ...

The development of tractable mathematical models of gradient-frequency nonlinear resonator networks is critical to advanced computer applications that require faithful computer simulation of human attention and/or perception. Conventional linear resonator models are computationally and analytically tractable, however tractability is achieved at the expense of capturing many significant features of ...

An innovative methodology, based on mechanistic models, will be developed for prediction of long-term (25+ years) durability of composites for the US Army's emerging facilities in different climatic zones. Accelerated testing simulating the Army's composites applications in various constructions and fields will validate it. Phase I developed the basic predictive tool using the Arrehenius principle ...

Cermet, Inc in collaboration with Georgia Institute of Technology proposes to develop spin Light Emitting Diode (LED) in a 24 month Phase II program. The spin LED is a simple yet powerful spintronic device that produces circularly polarized light and is a potent tool to quantify the spin injection efficiency and spin polarization efficiency.

After the successful demonstration of our Phase I approach, we propose to develop in Phase II a multispecific biowarfare electrochemical sensor for simultaneous detection of 5 toxins and 2 biothreat bacteria (anthrax spores, tularemia bacteria, botulinum toxin A, cholera toxin, staphylococcal enterotoxin B, Shiga toxin and ricin toxin). The sensor will utilize electrochemical aptamer-mediated prot ...

nGimat Co., in collaboration with the Georgia Institute of Technology, and the Wright-Patterson AFB Air Force Research Laboratory, proposes to develop a fuel injection method and advanced numerical simulation tools for injection of fuel at supercritical conditions in aero-propulsion combustors. This project is designed to accelerate understanding and commercialization of transcritical and supercr ...

Combustion powered actuation (COMPACT) is a flow control technology developed at Georgia Tech which utilizes a miniature combustion chamber (cubic centimeter scale) to produce high-speed pulsed jets suitable for aerodynamic flow control (separation control, drag reduction, shock control, etc.) at transonic or supersonic speeds. The system is lightweight, can be operated with passive fluidic valve ...
