This STTR Phase II program will create novel devices and system designs, expanding upon the microring resonator based silicon WDM modulator designs and system concepts developed during Phase I. The focus will be on linear transmitters and analog fiberoptic systems, used to transmit and transform analog signals, based on the Linearized - Ring Assisted Mach Zehnder Interferometer (L-RAMZI) modulator ...

ABSTRACT:In this effort, we will couple the energy of focused microwave bursts into the air and onto surfaces by first forming a laser plasma. The presence of the laser plasma allows much lower microwave intensities to couple their energy to the laser-pre-ionized surface or air- volume, allowing more efficient energy-transfer and the use of lower-power microwave systems to achieve the desired effe ...

ABSTRACT:The Munitions Environment Signature Model being developed by TSC will provide munitions design engineers with a tool for exploring RF fuze sensor alternatives by modeling the dynamic multistatic coherent RF signatures of targets illuminated by munition fuze sensors at sub-millimeter wavelengths. Output generated by the MESM will be suitable for use with radar imaging techniques including ...

ABSTRACT: A phase II program is proposed leading to integrate wireless inductive power transfer technology on two prototype tactical vests. The focus of the phase II program would be the development and evaluation of a full-scale inductive power transfer system on a PRC-152 radio by both modifying and interfacing its battery. Because a mating vest/pouch that contains inductive charging circuits so ...

ABSTRACT:Todays analysts need improved 3D visualization tools to assist in critical situations such as deconfliction, line-of-sight analysis, air space and satellite control.Currently available 3D displays cannot provide the level of detail and comfort needed because the displays contain unacceptable visual artifacts, do not provide full parallax, require special headgear, and induce nausea in man ...

ABSTRACT: Si photonic devices based on GeSn materials will be very important for the MWIR. The Air Force recognizes the need for next-generation high-performance photonic materials in the SWIR to MWIR infrared spectrum, due in part to the atmospheric high transmissive windows in this wavelength ranges. Due to materials limitations, silicon based photonic devices have not been utilized in this wa ...

ABSTRACT: Resodyn Corporation proposes to develop a portable, cost effective, near-surface residual stress measuring tools based on electromagnetic principles. Resodyn Corporation has patented technology developed for validating cold expanded button head rivet holes.The first application in Phase I is to apply this technology to countersunk cold expanded rivet holes in 7075 aluminum. In Phase I ...

ABSTRACT: Aircraft fuel cells are flexible rubber-coated fabric enclosures for the containment of fuel within aircraft cavities. The overall envelope dimensions and locations of interface fittings and attachment elements such as lacing ferrules and hanger baskets are critical to the proper function and durability of the fuel cells. The existing method of dimensional inspection is to install the f ...

Advanced thick composites are increasingly used in components for defense applications as well as commercial structures. The proposed project will lead to the development and commercialization of a validated predictive capability based on the Peridynamic (PD) theory to enhance the performance of thick composite components under complex loading conditions while exposed to harsh environments. The pr ...

ABSTRACT: This Phase II SBIR research addresses an important and timely technological need, specifically the practical development and demonstration of a very low-cost, multi-frequency, multi-beam phased array subarray technology. This low-cost subarray technology is the fundamental building block required for the practical realization of a large hemispherical phased array useful for horizon-to- ...
