Fine grained BST ceramics with high density has attractive properties including nonlinearity, low dielectric loss and high dielectric breakdown strength to realize high tunability. In Phase I program we demonstrated that modification of powder characteristics and composition in nano BST powder resulted in greater than 65% tunability at 250KV/cm with ~500KV/cm breakdown strength and Q value greate ...

FBS, Inc. and Penn State, during Phase I of its Air Force Phase I STTR contract, demonstrated high sensitivity defect detection in both isotropic metallic and anisotropic composite structures using a novel ultrasonic modal analysis technique (UMAT). The resulting technology which is a merge of vibration modal analysis and the ultrasonic guided wave technique has shown great potential for providing ...

The objective of this project is to develop extensions to Multicontinuum Technology (MCT) that enable accurate and efficient analysis of textile composite structures. In addition, probabilistic analyses will be performed to demonstrate the applicability of MCT for textile composite material selection and structure design. The project will build on the successful two-constituent MCT by generalizi ...

Impact Technologies, in collaboration with the Georgia Institute of Technology, the Rochester Institute of Technology and the Boeing Company, is proposing to complete the development, testing and evaluation of a novel biologically-inspired Micro Air Vehicle (MAV) conceptualized in Phase I and capable of agile and high endurance flight operations in dense and cluttered urban environments. Phase I a ...

In this Small Business Technology Transfer Program (STTR) - Phase II project we will build photonic integrated circuits that perform flip-flop and optical switching operations on silicon platform. These circuits are based on our Phase I work where we have established the feasibility of using coupled microdisk resonators and active waveguides coupled to a single microring resonator to realize bista ...

A new physics-based simulation capability will be developed based on high-order discretizations in both space and time for application to practical engineering problems involving complex physical phenomena and complicated geometries. The goal is to develop a tool which can accurately handle simulations of various important physical problems relevant to the aerospace industry and the DoD, including ...

In this Phase I STTR, Illuminaria, in collaboration with Professor Erickson’s Laboratory at Cornell University, designed and developed a practical liquid based reconfigurable photonic device photonic switch using low voltage microfluidic pumps and microfabricated optofluidic waveguides. Briefly, the basic element of this approach comprises a stream of high index of refraction liquid (core) micr ...

Esensors, with SUNY at Buffalo and SUNY at Albany as a subcontractor, will simulate, fabricate, experimentally investigate, evaluate, and deliver aprototype of a new adaptive IR photodetector based on advanced quantum dot (QD) structures. The detector’s operating principle is based on a new concept of the photoelectron lifetime tunable via adjustable potential barriers in QD structures. The phot ...

ABSTRACT: Protection of first responders who are exposed to hazards including chemical warfare agents (CWAs) is a very critical need. The need is derived from not only their welfare but their ability to respond, protect the community and provide logistical support to the response. A simple exposure monitor would provide critical information to the first responder and allow them to respond accor ...

ABSTRACT: The objective of this proposal is to develop efficient sensitivity analysis methods based on adjoint techniques for multi-disciplinary time-dependent problems. The approach is based on the discrete adjoint, which is derived and implemented on a software component basis, with the various multidisciplinary software components being linked together through a Python interface, thus preservi ...
