We propose the continued design, development and testing of spherical piezocrystal transducers and supporting technology including our gyroid transducer. The Phase II effort covers the modeling and demonstration of the gyroid transducer and comparison of performance with several piezocrystal and piezoceramic materials and testing in realistic environment. The electroacoustic performance will be es ...

The proposed project will undertake the research, design, and development of key concepts and technologies for a high-speed electronically tunable channel filter, based on monolithically integrated ultra-high-resolution super-compact grating (UHR-SCG) technology that has been developed in OptoNet. The grating will be realized on Silicon-Photonic Electronic-Photonic Integrated (EPIC) Platform that ...

Modern military systems contain numerous avionics and electronic systems that must perform to very high standards in hostile environments in the presence of numerous potential sources of electromagnetic interference (EMI). On airborne platforms for example, there could be dozens of RF systems radiating and receiving mission critical signals simultaneously over a very wide range of frequencies. Und ...

To overcome the capability gaps of current ECH suspension and retention liners, Hy-Tek Manufacturing Co. Inc. (HMC) will rely on a novel approach that significantly attenuates the transfer of low and high velocity impact energy to the soldiers head by vectoring a portion of that impact energy along a geometric plane tangential to the soldiers head. Unlike the functionality of current suspension an ...

Modern military and commercial aircraft include numerous RF systems and associated antennas serving a multitude of functions. The designed free-space performance of these antennas can be degraded by their installation on the airframe due to interactions with the platform, and the co-siting of so many RF systems creates enormous opportunity for undesired inter-system electromagnetic interference (E ...

MicroLink Devices and the University of Notre Dame propose to develop an ultra-lightweight, high-efficiency, GaAs-based, multi-junction solar cell that will be suitable for use in future platforms requiring very high specific power (>3.0 kW/kg) and very high areal power density (>370 W/m2). We will achieve this result by reducing the metal content of MicroLinks current inverted metamorphic (IMM), ...

In this Phase I SBIR program, QuesTek Innovations, a leader in the field of integrated computational materials engineering (ICME), proposes to design and develop novel aluminum alloys specifically optimized for the unique processing conditions and challenges of Additive Manufacturing processing. QuesTek is uniquely suited to rapidly designing new aluminum alloys specifically optimized for AM proce ...

Radar signatures of small boats and ships are inherently complex due to their myriad topside features: railings, antennas, masts, ladders, armaments, pilot stations, outboard engines, storage bins, etc. In boats, the use of fiberglass and other radar-penetrable materials for hulls and decks further complicates the radar signature by exposing interior geometry. Radar detection, identification, and ...

Yardney will design and develop a lightweight, safe, reliable, and cost-effective aircraft battery with improved thermal design and the use of active cooling techniques. As a novel part of the battery design, Yardney will investigate and implement high performance electrodes using three dimensional (3D) micro-porous current collectors, safer thin metal case cell design, a micro-channel heat pipe t ...

Active Electronic Scanned Array (AESA) radars play a strategic role in surveillance and reconnaissance. A GaN based T/R circuit will be radiation-hard but difficult to integrate with the remainder of the signal chain due to incompatible technologies. SiGe HBT technology, with its high frequency performance and the ability to blend in with CMOS, can act as a bridge between the high frequency III-V ...
