ABSTRACT: Chalcogenide glass fibers are commercially available and are used for delivery of mid-infrared wavelengths (1.5um to 6.5um).These fibers allow compact, robust and low-weight laser platforms designs.Laser systems in high-power and high-stress environments find their reliability and performance limited due to free-space optical components.Free-space components suffer from vibration and the ...

The recent success of ultra-high speed direct digital synthesizers (DDS) provides excellent solutions to waveform generation directly at radar bands. An arbitrary waveform generators operating at clock frequency close to 52 Gs/s with bandwidth greater than 26 GHz and dynamic range close to 80 dB would greatly improve transmitter performance for applications such as telemetry and multi-purpose RF s ...

In this program, HyPerComp and University of Michigan have teamedtogether to develop a high-order grid generator for Euler and viscousmeshes. The grid generator is based on HyPerComps successful generalpurpose CAD2Mesh software and is being integrated with HyPerCompsHDphysics and U. Michigans XFlow DG high-order solvers. High-order gridgeneration methods are being implemented to accurately capture ...

ABSTRACT: During Phase I, PaneraTech in partnership with UCLA-TANMS (NSF Center for Translational Applications of Nanoscale Multiferroic Systems) achieved a groundbreaking success by designing a multiferroic small antenna based on continuous spin rotation in ferromagnetic nanoelements in periodic electrode array patterns. Specifically, we developed Finite Elements Method (FEM) models to design nan ...

ABSTRACT: Global Engineering and Materials, Inc. (GEM) along with Columbia University propose to develop a simulation tool for modeling mixing process of multi-particle composite systems and generating the ultimate microstructure. A combined theoretical, numerical, and experimental approach will be developed to create a high fidelity software product with a reduced order modeling capability for an ...

ABSTRACT: Echo Ridge proposes to develop and deliver a suite of prototype EW training tools to support realistic warfighter training in the congested and contested RF environments expected in future operational engagements. The tools consist of an opposing force broadcast capability and an Electromagnetic Spectrum (EMS) monitoring capability which supports both electronic sensing (ES) and electron ...

ABSTRACT: The goal of this STTR is to design micro air vehicles (MAVs) capable of adaptively changing wing geometry utilizing novel active materials that overcome limitations of previous attempts at implementing practical biomimetic multifunctional structures. The basic idea of a morphing aircraft wherein the vehicle changes its shape to optimally perform in multiple flight segments holds the prom ...

ABSTRACT: Infrared sources and sensors are becoming increasingly useful for military and commercial applications. We propose to exploit recent advances in multimaterial fiber technology to produce a new class of optical infrared fibers that are robust and low in cost for high-power, high-stress environments. The use of beam confining fiber optics reduces or eliminates issues with misalignment or d ...

ABSTRACT: Our focus in this proposal is to perform basic research to create bio-inspired 3-D morphing mechanical structures which are a gateway technology to enable true 3-D morphing flight. Prioria and Virginia Tech University will team to perform basic research into bio-inspired structure such as artificial bones/wings/feathers and artificial muscles. Prioria will establish technical feasibility ...

This work will focus on the development of monolithic SWIR focal plane array technologies using CMOS or CMOS compatible fabrication technology. This will be realized on a Silicon substrate and incorporate APD+TIA arrays and be scalable to Megapixel arrays and coherent receiver operation for capture of the full optical wavefront vector information.
