ABSTRACT: In this effort, Freedom Photonics will develop a high-sensitivity high-resolution coherent imaging system based on a Si avalanche photodiode (APD) array and corresponding bias and read-out electronics. This will be a monolithic APD and ROIC (readout-integrated-circuit) focal plane array (FPA) system. We start from a proven high-performance CMOS electronics backplane and build the photon ...

ABSTRACT: To address the Air Force need for a nondestructive evaluation technique applicable to energetic composites with low density gradients, Luminit, LLC, and Southern Illinois University Intelligent Measurement and Evaluation Laboratory propose to develop a new Compression Imaging Phase Array Ultrasound Interrogator (CIPHOR) system based on phased array higher frequency ultrasonic imaging. ...

ABSTRACT: The Triton team proposes to develop techniques for fabrication and characterization of high performance biofunctionalized field effect transistors (bio-FETs) for sensing applications. Nanoscale electronic materials such as silicon nanowires, carbon nanotubes and graphene are promising materials for biosensing applications. Field effect transistors (FETs) using nanomaterials have been de ...

ABSTRACT: Two accelerating trends in military aircraft design and development are apparent: (1) increasing system capabilities in terms of weapon systems, ISR payloads, guidance, navigation and control (GNC), etc., enabled by ever-smaller and evermore capable electronics; and (2) reduction in overall size and available space for auxiliary equipment (and associated wiring, etc.) to measure and asse ...

ABSTRACT: We exploit recent advances in magnetoelectric/piezoelectric (ME/PE) composite materials to enable the development of efficient sub-wavelength radio frequency (RF) transmitting antennas. With these materials will be possible to achieve high dielectric permittivity and magnetic permeability, slow electromagnetic propagation and low RF loss tangents. Together, these special properties m ...

ABSTRACT: Energetic composite materials comprise crystalline energetic particles embedded in a polymer matrix. There is a need to gain insight into the microstructure and damage mechanisms of energetic composites via nondestructive evaluation. Applications of x-ray computed micro-tomography to resolve the microstructure of energetic composites are challenged by the low density gradient between th ...

ABSTRACT: In this proposal, researchers from Cascade Technologies and Professors Matthias Ihme and Ali Mani from Stanford University lay out a plan to develop predictive modeling tools for transcritical flows. Phase I of the three phase plan is outlined in detail and extensions are proposed for Phases II and III. Central points of the Phase I plan include: A comprehensive review and assessment ...

ABSTRACT: This effort is a close collaboration between RMD and Alfred University. Our goal is to develop a process for producing optical ceramics with properties approaching or exceeding single crystals. Ceramic processing can provide enhanced performance, lower cost, higher yield, relaxed constraints on size and shape, and materials that are difficult or impossible to grow as crystals. We will ...

ABSTRACT: We propose here a robust production-level high-order mesh generation software for complex geometries. High order accurate numerical methods are becoming increasingly popular in the present time and have demonstrated a great measure of success in efficient error-controlled simulations for a wide variety of important problems. A curved geometry and mesh generation system is essential in m ...

ABSTRACT: In this proposal, a team comprising ParaSim Inc. and the University of Utah will examine the feasibility of generating curved high-order meshes from hybrid linear meshes while retaining a given boundary geometry. Specifically, a preliminary design of a software package for creating high-order (up to 4th order and higher) hybrid-element meshes for complex geometries will be developed. S ...
