"This SBIR Phase I project focuses on the implementation of a new THz module that can emit coherent and tunable THz waves. Recently, coherent THz radiation was generated at room temperature by PI, with a tuning range of 56.8-1618 ¿m (5.27 - 0.18 THz), inGaSe based on difference-frequency generation. The peak THz power can be as high as 69.4 W at 196 ¿m. The corresponding photon conversion effici ...

"M Cubed has conducted preliminary work to fabricate near-zero coefficient of thermal expansion (CTE) fiber reinforced ceramic composites. These composites have high specific stiffness and thermal stability (thermal conductivity/CTE). M Cubed has alsodeveloped ways to rapidly polish surfaces of various materials to Angstrom level surface finish. In the proposed program, these technologies will be ...

"M Cubed has developed three key processes for manufacturing advanced materials components which include PRIMEX, DIMOX and reaction bonding. The processes have been used to make a variety of components for commercial and military systems making themlighter, stiffer, highly functional and resistant to many threats. However, market penetration has been achieved only in high value added commercial pr ...

"The overall goal of this proposed program is to develop fiber optic Raman spectroscopy as an on-line analyzer capable of optimizing the mechanical properties of composites during manufacture. Phase I will demonstrate feasibility by developingrelationships between reaction mechanisms measured by Raman spectroscopy and mechanical properties measured by rheology for epoxy resin as a model system, w ...

"Direct detection radar requires both AD and DA conversion located essentially at the antenna or at the LNA output. The advantages are dramatic improvements in EMI interference and dynamic range and a reduction in power and complexity. For example with RFat 2 - 10 GHz, the down conversion process could be eliminated by direct digital conversion if sampling at 20GS/s were possible. In addition, an ...

Clocks and pulse sources are critical elements for next generation IC¿¿s such as DSP¿¿s and ¿Yprocessors which depend critically on stability and jitter. Clock skew becomes significant because of the large chip dimension. ADC¿¿s and DAC¿¿s are mixedsignal circuits which demand extremely precise clocks at multi GB/s rates. Telecommunication transceivers and transponders ...

True time delay (TTD) is essential for optically coupled phased array radars. How to implement the phased array is not so clear since a complete manifold of delays for transmit and delays must be implemented without introducing glitches associated withswitching. In a continuous transmit and receive mode, it is difficult to interrupt the operation to implement a new TTD delay combination in a noi ...

"Phase I efforts will research requirements for a low-fidelity simulation that address a layered Ballistic Missile Defense System (BMDS) for all phases of missile flight and all ranges. Phase I also will demonstrate a Missile Defense Concept Analysis Tool(MiDCAT) concept for new and evolving BMD systems (GMD, MEADS, THADD, Navy TWD, TBMD, etc.) and Ballistic Missile Command, Control, and Communica ...

This SBIR program is aimed at improving the power density of primary silver-zinc cells in general, and particularly those used in interceptor ballistic missiles. We intend to achieve that objective by advancing the state-of-the-art of bipolar electrodes,where both positive and negatives are built on a common current collector, and of the "pile" batteries made with them, which are capable of up to ...

Lithium-ion batteries offer several performance advantages over conventional rechargeable batteries including higher specific energy ( 150Wh/kg), energy density (>325 Wh/L) and cycle life. While these advantages have lead to the recent growth oflithium-ion technology for various consumer applications, this technology still needs development to be used in some non-commercial applications that requ ...
