Global Technology Connection, Inc., in collaboration with academic partners, Georgia Tech"s Center for Innovative Battery and Fuel Cell Technologies, Penn State University, and industrial partner Eagle Picher propose to create a physics-based modeling for predicting the life performance of Low and Middle Earth Orbit (LEO/MEO) Lithium-ion cells. The relationships between solid-electrolyte interpha ...

An innovative, super-miniature, fast-switching array-based photonic time delay device is being developed for the active electronically scanned-array (AESA) MDA and Navy radars. The design is based on the fast electro-optic effect, the super miniature fiber-lens collimation array, and the existing WDM photonic true time delay technologies. In Phase I Agiltron has successfully demonstrated the core ...

Triton Systems, Inc., proposes to transition a proof of concept cryocooler developed under the MDA STTR Phase I effort, to a miniaturized cooling system that will have commonality and reducibility to serve multiple MDA missions. The proposed cryocooler uses a novel standing wave design to achieve the miniaturization and low weight needed for MDA focal plane array cooling systems. This cryocool ...

This STTR program, Topic MDA07-T011, aims at developing an array radiator for low-cost X-band planar phased array antenna with over 50% reduction in LCC (life-cycle cost), which currently is prohibitively high. The phased array must be planar, wideband, and compatible with the fabrication process of low-power T/R modules. In Phase-I, Wang Electro-Opto Corporation (WEO), Ohio State University, and ...

Radar targets provide a rich scattering environment that produces from 5-25 dB target fluctuations. The spatial dependence of target scattering means that targets produce essentially independent scattering returns when radiated from sufficiently different directions. Thus, if receivers are distributed over a wide enough area, which is the premise of the multiple input multiple output (MIMO) radar ...

Cermet, in collaboration with researchers at Georgia Institute of Technology, proposes to implement a lattice matched III-Nitride technology using existing substrates. The implementation of a lattice matched substrate promises to produce near dislocationfree III-Nitrides for the first time while the use of an existing substrate technology dramatically lowers development cost and reduces the devel ...

Single-crystal aluminum nitride substrates will be used for epitaxial growth of GaN by hydride vapor phase epitaxy (HVPE). The relatively close match in crystal structure, in chemical compatibility, and in thermal expansion should allow much high quality(and much thicker) GaN layers to be grown. HVPE will allow these GaN epitaxial layers to grown cost effectively.Extremely high power microwave ...

Hybrid Technologies (HT, Amherst, NY) in cooperation with the Institute for Lasers, Photonics and Biophotonics (ILPB) at the State University of New York at Buffalo proposes to develop new bulk glass-photopolymer materials and investigate the feasibilityof using them for high efficiency, permanent, highly wavelength selective holographic gratings needed for Dense Wavelength Division Multiplexing ( ...

Silicon has long been the semiconductor of choice for high-voltage power electronic applications. Recently, SiC has attracted attention because SiC is projected to have better performance than silicon. [1] SiC power switching devices have yet to becommercialized, largely due to SiC crystal defects, most notably the device-killing micropipe defect, which does not permit high total current parts t ...

A random access, solid-state, optical cross-switch capable of 770 channel discrimination in the telecommunications C-band is designed and proven as an alternative to current thin-film WDM devices and as a mechanically robust alternative tomicroelectromechanical (MEMS) WDM devices. The device may be used in multiplexing (mux), demultiplexing (demux), or complete cross-switch configurations, and is ...
