ABSTRACT: We exploit recent advances in magnetoelectric/piezoelectric (ME/PE) composite materials to enable the development of efficient sub-wavelength radio frequency (RF) transmitting antennas. With these materials will be possible to achieve high dielectric permittivity and magnetic permeability, slow electromagnetic propagation and low RF loss tangents. Together, these special properties m ...

ABSTRACT: Digital binocular helmet-mounted display (HMD) systems are now available that allow high resolution wide field-of-view (WFOV) digital imagery to be displayed on high resolution microdisplays. These digital HMD systems require a low-latency embedded vision processor (LLEVS) capable of implementing the necessary image processing algorithms. An SA Photonics LLEVS will be implemented on next ...

ABSTRACT: FIRST RF has teamed with University Research Foundation (URF) and Radiometrics Corporation to develop a passive radiometer-based geolocation system for use with a wide variety of USAF platforms. The system will be comprised of a ruggedized, near-COTS radiometer system by Radiometrics Corporation, augmented with a robust 2-D scanning beamsteering antenna by FIRST RF Corporation and enhanc ...

ABSTRACT: Speech recognition technology is in wide use today and has been successfully integrated in a number of applications. Most of these applications require a microphone located near the talker. However, when a distant microphone is used where the speaker is at some distance from the microphone as in a hands-free communication, or in a meeting room, there is a major problem with the captured ...

ABSTRACT: In this proposal, a team comprising ParaSim Inc. and the University of Utah will examine the feasibility of generating curved high-order meshes from hybrid linear meshes while retaining a given boundary geometry. Specifically, a preliminary design of a software package for creating high-order (up to 4th order and higher) hybrid-element meshes for complex geometries will be developed. S ...

ABSTRACT: Two accelerating trends in military aircraft design and development are apparent: (1) increasing system capabilities in terms of weapon systems, ISR payloads, guidance, navigation and control (GNC), etc., enabled by ever-smaller and evermore capable electronics; and (2) reduction in overall size and available space for auxiliary equipment (and associated wiring, etc.) to measure and asse ...

ABSTRACT: This effort is a close collaboration between RMD and Alfred University. Our goal is to develop a process for producing optical ceramics with properties approaching or exceeding single crystals. Ceramic processing can provide enhanced performance, lower cost, higher yield, relaxed constraints on size and shape, and materials that are difficult or impossible to grow as crystals. We will ...

Experimental data from a number of DoD supported research programs have indicated that electrical systems capable of producing highly repetitive bursts of high voltage, fast risetime pulses are a critical enabling technology for applications tied to nonequilibrium physical processes, such as combustion, boundary layer flow, and the generation of high power EM waves. Recognizing the important role ...

ABSTRACT: An unseeded measurement technique is proposed for simultaneous spatially-resolved measurements of density, temperature, and velocity in hypersonic wind tunnel flows with the future potential for time-resolved measurement capability. A variant of filtered Rayleigh scattering (FRS) will be developed that takes advantage of unique monotonic relationships between molecular vapor cell filter ...

ABSTRACT: In this effort, Freedom Photonics will develop a high-sensitivity high-resolution coherent imaging system based on a Si avalanche photodiode (APD) array and corresponding bias and read-out electronics. This will be a monolithic APD and ROIC (readout-integrated-circuit) focal plane array (FPA) system. We start from a proven high-performance CMOS electronics backplane and build the photon ...
