The leakage of electromagnetic (EM) energy into air vehicles, and particularly into ordnance, poses a hazard that requires careful evaluation. Under current guidelines, such evaluations are primarily to be carried out through extensive testing of items under possible field conditions, a process that can be both time-consuming and costly. The scope of this STTR Phase I activity is to implement a h ...

The present text proposes development of efficient, accurate and rapidly-convergent algorithms for the simulation of propagation and scattering of electromagnetic fields within and around structures that (i) Consist of complex combinations of penetrable materials as well as perfect and imperfect conductors, and, (ii) Possess complex geometrical characteristics, including open surfaces, metallic c ...

Recent advances in dielectric and magnetic materials have spurred renewed interest in the field of solid state pulse and RF burst generation using Non-Linear Transmission Lines (NLTL) . The NLTL approach to HPM and UWB generation eliminates the need for an electron beam, vacuum system and magnets required in conventional HPM sources. Furthermore, the novel waveforms of NLTL generated pulses promi ...

Aerosol Jet printing is proposed as a method for printing large area, CNT-based transistor arrays on flexible substrate. The teaming relationship combines expertise in high resolution printing along with device and materials expertise. All semiconductor, dielectric, and conductive materials comprising the TFTs will be solution processed and printed with a single machine. This will lead to a cos ...

ABSTRACT: Adversarial installations, such as those housing the means for nuclear weapons production, are increasingly being constructed in heavily fortified locations and often using ultra high performance concrete (UHPC) as the construction material. As such, the U.S. Air Force has considerable interest in further developments of ultra high performance concrete (UHPC) to maintain an advantage o ...

Detecting explosives and weapons under clothing or in hand carried packages, and imaging terrain and objects through fog and smoke are two high-priority needs that can be met using light in the Terahertz frequency range. However, to image concealed threats, and aid in navigation in fog and smoke, a practical, low cost THz camera is needed. Intelligent Optical Systems (IOS) in collaboration with Re ...

ABSTRACT: The U.S. Air Force has a need to develop a new class of advanced, wide field of view (WFOV) imaging sensors that sample the radiation field in multiple modes: spectral, temporal, polarization, and detailed object shape. These multimodal sensors are to be deployed on high altitude drones to enhance their intelligence, surveillance, and reconnaissance (ISR) capabilities. Smaller versio ...

ABSTRACT: Tanner Research, Inc., in collaboration with University of Maryland, will determine feasibility and plan for development of technology based on insect visual sensing and processing, which will integrate three modes related to navigation and guidance: motion detection from imaging sensing; polarization sensing and processing to implement a celestial compass; and ocellar sensing and proce ...

ABSTRACT: To address the Air Force"s need for a novel advanced imaging sensor concept that samples all of the information in the radiation field, taking inspiration from biological systems, Luminit proposes to develop a new Biomimetic Integrated Optical Sensor (BIOS) system. The system will be based on the unique integration of a wide field-of-view (FOV) miniature staring multi-aperture compound ...

The proposed work aims at detailed investigation of Carbon Nanotube Field-Effect Transistor (CNTFET) device design and its impact on Radio-frequency (RF) circuit performance in comparison to Si-MOSFETs and related circuits at the same channel lengths. The goal is to establish a geometry scalable CNTFET compact model for RF circuit design and determine its parameters based on characteristics from b ...
