Herein, we propose a novel approach to achieving a broadband, phased-array transmitter operating at frequencies from 100-300 GHz. Our approach is based on the concept of optically distributing a pair of locked optical tones to an array of antenna coupled photomixers. Lightweight optical fibers enable the distribution of these optical tones to any arbitrary antenna array geometry with antenna pla ...

Proposed is the development of a High Efficiency Mobile Ice Maker (HEMIM) for the Army that is capable of integrating DC power from solar PV cells. The proposed ice maker will include a variable capacity vapor compression system with variable air flow as per ambient temperatures. The Performance of the high efficiency cycle will be enhanced by the use of advanced variable speed drive and pulsating ...

In this proposal, AlphaSense, Inc. proposes to develop an innovative real time probe for online monitoring of plastic bonded explosive manufacturing process. Key innovations of the proposed sensor probe include: a) the use of a white light interferometer (WLI) to form real time images of the particles for accurate particle size measurements, and b) the use of quartz crystal microbalance (QCM) base ...

Mid-infrared (MWIR, wavelength ~10 micron) imaging has significant importance in military surveillance and target recognition, since human body radiation peaks in MWIR. The GaSb/InAs type-II Strained Layer Superlattice (SLS) MWIR detector has been under intensive investigation recently. While much progress has been made to enhance wavelength coverage, one of the few remaining issues has been its r ...

Low light level infrared imaging has significant importance in military surveillance and target recognition. The proposed broadband low-light-level nano-BiCMOS camera covers visible and near infrared bands from 400 nm to 1,550 nm wavelengths. With a proven nano-technology, the proposed nano-BiCMOS photo-detector solves this long-standing tradeoff between quantum efficiency and dark current by in- ...
