ABSTRACT: In order to effectively utilize multiple Unmanned Aerial Vehicles (UAVs) for missions such as Intelligence, Surveillance, and Reconnaissance (ISR), Strike, etc., it is vital to have Open Architecture (OA) tools that accurately model and simulate the interaction of autonomous, unmanned, and manned air vehicles. Daniel H. Wagner Associates (DHWA) proposes to develop automated, efficient, O ...

ABSTRACT: Recently quantum cascade lasers (QCLs) and interband cascade lasers (ICLs) have progressed steadily in the 3.5 10 m range with optical powers < 0.5 W. However, these devices rely on complicated band alignment and large numbers of repeating quantum wells which pose significant challenges in device fabrication. Furthermore, the sub-Watt power limitation and poor wall-plug efficiencies (W ...

Objectives and Intellectual Merit: The infrastructure of modern civilization is a set of complex systems1 that dynamically interact across multiple layers of abstraction. Researchers from many disciplines2 are designing analytical tools for predicting the global and local behaviors of these complicated, multi-layer networks. Easily usable, available (open source) and inter-operated tools are neede ...

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, ...

ABSTRACT: Remarkable advances in artificial intelligence (AI) and human-systems integration are providing aircrew with cockpit automation systems of unprecedented sophistication. Onboard intelligent assistants monitor the aircraft, interpret and carry out pilot commands, and advise the pilot (onboard or remote) as to aircraft and system status, mission progress, threats and alerts. Because pilots ...

ABSTRACT: The objective of this proposal is to demonstrate the feasibility of a flexible, low-cost, integrated and sensitive broad spectrum optical property characterization system. We propose a hyperspectral imager designed for operation in the 300nm 2000nm spectral region with state-of-the-art spectral and spatial resolution through the use of a high density array of high finesse (F = 1000) tuna ...

ABSTRACT: This Phase I STTR project aims to develop a silicon friendly carbon nanotube field effect transistor platform technology with reduced contact resistance and wafer-scale aligned carbon nanotubes towards development of an L-band amplifier. Key innovation nuggets that will be developed include: 1) a wafer scalable process to deposit dense aligned arrays of high purity semiconducting and len ...

ABSTRACT: In this project, we propose to develop the baseline process to form low source-drain contact resistance to the CNTs. This includes finding the right metal stack and annealing recipe to form good ohmic contact to the CNTs. The goal is to achieve a resistance less than 25 k at per nanotube contact. To reach such goal, we will leverage the interfacial dipole alignment of conjugated polyelec ...

ABSTRACT: Carbon nanotubes (CNTs) have great potential for high performance RF applications. Theoretical study has shown that the electrical current in a CFET is intrinsically linear. Today, linearity is the underlying limitation in increasing the data transport densities of wireless networks. The complex modulation protocols used to achieve higher data rates requires linear amplifiers. Increasing ...
