Dismounted soldier batteries play a critical role in the agility and effectiveness of US Army soldiers. Current state of the art graphite anode based lithium ion batteries are becoming very ineffective due to limited specific energy values of

Existing wired and wireless communication systems are simplex, also called half-duplex. The transceiver nodes today either transmit or receive at a given time. Typically, a Frequency Division Duplex (FDD) system is used by radios to transmit and receive at the same time but at different frequencies. GenXComm has developed the world’s first wide-band, small-form-factor single frequency simultaneo ...

Dense Urban Environments (DUE) are characterized by large concentrated populations that tend to cluster into groups networked together by common interests and needs. Populations cluster along political, social, cultural, ethnic, economic and other social lines. Networks among these groups, formed along lines of shared characteristics, are often in friction with one another as they contend over sca ...

There is a developing need for a low-cost high performance eSWIR infrared detector technology that can operate at room temperature with a cutoff wavelength of 2.5 microns. Over the years, many new and innovative technologies have emerged that have made some progress towards this goal, but the gap between the quantum efficiency and cutoff wavelength with room temperature have been difficult to brid ...

The highest performing infrared (IR) detectors are fabricated from alloys of HgCdTe (MCT) grown by molecular beam epitaxy (MBE) on lattice-matched substrates. Although the best performing IR detectors, MCT-based imaging arrays exhibit higher than anticipated noise, especially random telegraph noise (RTN) that occurs in seemingly random sets of pixels. It is presently believed that RTN originates f ...

Field effect transistors (FETs) based on alloys of AlGaN are the current state of the art for the switching and amplification of radio frequency (RF) signals, as would be used in radio communications, RADAR systems, and power conversion and control devices. A significant problem preventing AlGaN-based devices from realizing their true potential is the presence of dislocation defects that result fr ...

The objectives of this SBIR include the development of a modeling framework to predict mechanical properties of as-manufactured AM parts accounting for microstructure. The final product will (1) accept a reconstruction of the interior and exterior geometry of structural component including accurate 3D measurement of defects using x-ray computed tomography (CT); (2) allow for input of material prop ...

The cryogenic temperatures required for many detectors limits their viability on small platforms including personnel vehicles, UAVs, and smallsats. The removal of cryogenic cooling devices could decrease the overall sensor system complexity and price, as well as total footprint and mass, resulting in multiple reductions in cost. Recent advances in microfabrication have enabled smaller, higher oper ...

Sivananthan Laboratories proposes to design an electron-beam induced current (EBIC) platform capable of performing high-resolution carrier lifetime, mobility and diffusion length measurements at point and extended defects in small-band gap semiconductor interfaces for infrared detectors. The proposed design includes a micro-electro-mechanical systems (MEMS)-based double-tilt heating stage and will ...

Type II InAs/GaSb strained layer superlattices represent promising material system capable of delivering more producible, large-format MWIR/LWIR focal plane arrays (FPAs). However, no viable planar processing techniques have been demonstrated for T2SL – they currently rely on mesa isolated diodes. These mesas require etching, and passivation, which complicate processing and reliability. It’s d ...
