The design ofDeployable Reconfigurable Pixelated Antennas (DERPAs) that can operate at different frequencies,with different radiation patterns, and achieve polarization diversity is proposed.The solution proposed, based on optically pixelated silicon or GaAs surfaces, can be used as reflective surfaces for reconfigurable reflect arrays or as reconfigurable active and modular antennas. The optical ...

ABSTRACT: Material extrusion 3D printing is an Additive Manufacturing method which utilizes a polymeric monofilanment as a feedstock in the fabrication of 3D objects. The relative simplicity compared to other AM technologies makes it an attractive manufacturing tool, however, characteristics inherent to this 3D printing method (namely air gaps between print rasters) makes it undesirable for the 3D ...

Micro-RDC proposes to demonstrate the feasibility of developing low-cost, low-weight, reliable packaging materials and processes to produce low-power advanced Integrated Circuits (ICs) that can operate continuously at temperatures between -55C and +225...

In partnership with the Strausfeld Lab at the University of Arizona, BNS proposes to develop an Amplitude and Polarization High-speed Image Display (APHID) based on our previous VIS/NIR Hyperspectral Image Projector (HIP) design. Using BNS-developed liquid crystal (LC) spatial light modulators (SLMs), this display will provide high-speed multispectral wide-field visual stimulus to invertebrates ov ...

Terrorist use of radioactive nuclear materials via nuclear and/or radiological dispersion devices (dirty bombs) is a serious threat. Therefore, it is critical to detect the proliferation of nuclear material. Critical challenges facing this objective include: (a) high sensitivity detection of signature emissions (e.g., gamma rays) from common radioactive isotopes behind shielding, and (b) cost-effe ...

ABSTRACT: A range segment upgrade for Air Force satellite control network (AFSCN) will significantly improve system effectiveness via spectrum sharing and seamless interoperation. However, the upgraded system requires new capabilities such as real-time and accurate RF interference detection and mitigation, array antenna backlobe/sidelobe suppressions, accurate performance degradation prediction, ...

Stellar Science, in collaboration with the University of Maryland, proposes to develop algorithms to demonstrate the feasibility of constructing three-dimensional (3D) models of satellites using ground-based imagery on a standard PC in under 15 minutes. The Phase I effort will address the challenge of registering two-dimensional (2D) images of satellites where traditional feature matchers frequent ...

The proposed Small Business Technology Transfer (STTR) Phase I project will determine the technical feasibility and cost-effectiveness of utilizing emerging blended-reality technologies that enable interoperability with LVC simulations to create more effective and comprehensive Battlefield Airmen training environments. The proposed training technologies will be integrated across multiple platforms ...

A compact laser driver will allow photoconductive semiconductor switches to be used in small EMP simulator "building blocks" (EMPBB). Combined with a battery powered on-board pulsed power system, these EMPBBs will allow the construction of flexible EMP test facilities with nothing more than a single fiber optic timing connection to each EMPBB.

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 ...
