We propose to bandgap engineer the InAs/GaSb/AlSb material system to realize a dualband focal plane array (FPA) made up of stacked multi-barrier Type-II strained layer superlattice (SLS) photodiodes. Two longwave infrared spectral bands will be imaged in alternate frames by using a readout multiplexer that flips the voltage bias across the FPA from frame to frame. In Phase I, we will develop and ...

The objective of this program is to develop and produce a prototype SM-3, Block IIB nosecone that can achieve all of the performance requirements specified for the IIB interceptor, but at a considerably lower cost and weight than has been achieved previously with SM-3 nosecones. This is achievable with technologies developed at Mentis Sciences, Inc., and is being applied to a number of other inte ...

Triton Systems proposes to develop advanced methodologies, for protection of Critical Program Information (CPI) of BMDS assets against exploitation by reverse engineering and tampering through the use of Side Channel Attacks (SCAs) on Field Programmable Gate Array (FPGA) devices. Specifically, a method to confuse and defeat SCAs that utilize timing information and electromagnetic leaks will be de ...

Thermal batteries are a power source for most MDA weapons systems. Some of these systems have severe constraints on weight and size, and for this reason, advanced thermal batteries are needed that can provide greater power in smaller and lighter packages. The key components of conventional thermal battery cells are made by hydraulically pressing powders. Such components must be greater than a m ...

The ballistic missile defense system (BMDS) has been established to protect the American people, their allies and troops deployed abroad. The mission capability and success of many of the elements comprising the BDMS are reliant on more efficient and capable portable power supplies. Aspen Aerogels proposes to develop next generation thermal insulation solutions specifically for use in primary re ...

Users of phased arrays with large numbers of elements (e.g., 40,000 to 400,000) wish to have the capability of steering multiple beams simultaneously and to maximize the array bandwidth and dynamic range. Optical fiber"s light weight, small size, and immunity to electromagnetic interference have motivated researchers to propose photonic techniques for steering large arrays. In Phase I of the SBI ...

Active phased array radars are expensive and solid state power and low noise amplifiers are a major component of that expense. Phase shifters employing low loss, high linearity Radio Frequency (RF) Microelectromechanical Systems (MEMS) switches are an enabling technology for Electronically Steerable Antennas that can be employed for radar and Electronic Warfare applications. This program will deve ...

The goal of this proposal is to develop fast wafer-scale techniques for characterization of Zn-concentration and precipitates and inclusions of Cd and Te. A novel approach to spectrometry will be used to develop a fully automated system for generation of high resolution 2D map of Zn-concentration that promises to be 10x-100x faster than current spectrometers. Advanced image processing techniques ...

Under a recently completed Air Force SBIR Phase II program, we demonstrated the initial feasibility of a back-illuminated p-on-n LWIR HgCdTe junction photodiode formed by diffusion of arsenic from a vapor source. This initial successful demonstration used a mesa format. Our proposed Phase I program will continue the development of the basic arsenic-vapor-diffused lateral-collection micro-junct ...

Triton Systems, Inc. proposes an innovative nanostructured anode material for use in advanced high-energy-capacity space-rated lithium-ion batteries. The new anode material has the possibility of increasing the capacity of lithium-ion batteries by a factor of 10. The deposition processes used to manufacture the anode are non-vacuum-based and large area, lowering the cost in production of the ano ...
