The goal of this program is to develop a low cost, flexible manufacturing method for the production of high temperature ceramic composites for rocket propulsion systems. The matrix materials selected for this program will be ZrC, HfC, and TaC. These-materials have good oxidation/corrosion and ablation resistance at elevated temperatures, but typically do not possess the thermal shock resistance an ...

A novel beamforming network is proposed to electronically scan two independent beams in a conformal phase array. The beamformer utilizes ferroelectric materials in the RF distribution network to control the amplitudes and phases of the array element excitations. One beamformer board is required for each beam and four low power DC voltages per beamformer are needed to achieve total hemispherical ...

Big Light Technology, Inc. proposes to develop a light weight, comfortable, flexible, form fitting instrumented garment. The instrumented garment will be capable of monitoring the skin temperature at multiple localized torso locations using fiber-optic sensors incorporated on a single optical fiber. The sensors are passive and will therefore require no external power. The method for monitoring ...

A long-standing trend in the integrated circuit industry is to reduce pattern geometries on semiconductor substrates. To continue this trend, the next exposure wavelength after on-going deep-ultraviolet (248 nm) will be 193 nm. This SBIR Phase I program will identify and develop thermosetting bottom anti-reflective coatings (BARCs) meeting requirements for use with 193 nm unilayer resists. A serie ...

Ion-implanted, thin polymer films exhibit a large temperature coefficient of resistance which suggests their application in microbolometer arrays used for infrared ( IR) imaging and temperature mapping. Compared to current microbolometer designs which require a series of difficult deposition steps, an ion-implanted polymer-based device requires only a single layer which can be applied by spin coat ...

Future spacecraft will require efficient heat transport at 60K Or lower, and will require flexible and thermal diode features. Cryogenic flexible heat pipes and capillary pumped loops have been developed, but are not capable of adverse tilt operation and rapid, autonomous startup. Loop heat pipes with advanced fine pore evaporator wicks show promise for meeting future needs, provided that rapid, a ...

Epitaxial Technologies proposes to develop innovative material structures for Auger transistors that can be used for millimeterwave oscillators. We will achieve this objective by performing device designs to determine suitable material structures and epitaxial growth processes. The primary goal of this proposed Phase I effort is to demonstrate the feasibility of Auger transistors by developing te ...

Epitaxial Technologies proposes to develop novel material and device tech, nologies using antimony-based active channels for highly linear microwave devices that can be used to simultaneously produce low noise and high power. To do this, we will perform materials and device design to determine suitable material structures and epitaxial growth processes. The main goal of this proposed Phase I effo ...

The recent demonstration of twist bonded GaAs substrates offers the potential to develop universally compliant substrates upon which almost any III-V or related semiconductor can be grown without lattice mismatch induced defect formation. Compliant substrates would rapidly expand and improve a number of device applications, such as Sb-based detectors and a wide range of InGaAlAsP devices, which ar ...

Development is proposed of a new, rotary form of Stirling cryocooler which offers longer operating life and much lower vibration than reciprocating forms of cryocoolers. The proposed machine has fewer moving parts to wear and can be completely balanced to eliminate vibration in all planes by simple counterweights on the shaft, which is not possible in reciprocating machines. The rotary desi ...
