The Phase-I effort has produced three key results as the foundation for the Phase-II proposal. First, vector network analyzer measurements of a Bacillus subtillis (an Anthrax surrogate) sample has yielded promising absorption signatures around 425 and 445GHz. These are believed to be the most accurate measurements ever made of an Anthrax-like biopaticle in the sub-1.0 THz region. Second, the ke ...

InnoSys and Purdue University propose to research and develop robust designs for building, implementing and demonstrating a new class of terahertz (THz) vacuum electronic device (VED) power amplifiers and power sources at frequencies in the range of 0.3-3.0 THz (the so-called THz regime) employing advanced micro electro mechanical system (MEMS) technology and processes. There is significant inter ...

A new spectroscopic instrument – a time-domain terahertz ellipsometer (TDTE) – and the associated techniques for characterization of advanced materials in the terahertz (THz) spectral range will be developed. A novel three pole Auston-type switch will serve as the detector which is capable of simultaneously measuring two electric field polarizations. Standard THz time domain spectroscopy requi ...

We aim to undertake a Phase I study of multiferroic heterostructure thin film composite materials (CoFeB / PMN-PT) and their applications in high frequency (>10GHz) microwave passive circuit building blocks. In this Phase I investigation, Aneeve Nanotechnologies together with Prof Charles Ahn (Yale University) and Dr. Pedram Khalili (UCLA) will develop multiferroic heterostructure systems to demon ...

In this proposal, Boston Applied Technologies, Incorporated (BATi) together with University of Minnesota proposes to develop a high quality epitaxially grown multiferroic thin film heterostructure through a simple wet chemical route, which has been demonstrated the capability of growing high quality multilayer films through nano-engineering and introducing proper buffer layers. The feasibility of ...

Physical Sciences Inc. and Prof. Seth Bank at the University of Texas Austin will develop thin-absorber avalanche photodiodes based on digital alloys of AlInAsSb for high-performance photodetection between 2.0 – 2.5 μm. The AlInAsSb quaternary alloy system allows for compositional grading throughout the device structure, enabling novel photodiode architectures inaccessible with other III-V allo ...

Sonalysts, Inc., along with Worcester Polytechnic Institute (WPI) and Advanced Interactive Systems (AIS), proposes to investigate the feasibility of developing an approach for modifying an existing intelligent tutoring technology and a simulationenvironment so that an intelligent tutor can be paired with a user engaged in a simulated dismounted infantry training exercise. The goal of this approac ...

During Phase I Sonalysts, Inc., Worcester Polytechnic Institute, and Advanced Interactive Simulations, collaborated to investigate the feasibility of producing a training system that, using a simulated urban environment, supplies instructional interventions (such as real-time feedback) that are pedagogically sound and contextually relevant to the Soldier engaged in first-person simulated training. ...

Triton Systems, Inc. along with our academic partner have reviewed the commercial and academic literature on chalcogenide glasses that have high transparency in the near infrared.  Based on this, as a team we have identified potential ChG compositional ranges that could meet the Navy's stringent requirements.  We will use prediction analysis based on prior work from our partner to predict likely ...

Embedded systems have become increasingly popular over the past years, both in civil and military applications. The probability of an embedded system to perform the required operations during the specified period of time, i.e., the reliability, depends on both the underlying hardware reliability and software reliability. The traditional approach to predict the software reliability on the basis of ...
