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 ...

Carbon nanotubes (CNTs) have great potential for high performance RF applications. Theoretical study has shown that the electrical current in a CNT field effect transistor (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 am ...

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 ...

The proposed project will focus on qualifying amorphous-iron Particle Reinforced Metal Matrix Composite (PRMMC) coatings as replacements for Electrolytic Hard Chrome (EHC) and HVOF WC- Co wear and corrosion resistant coatings on high-strength steel components. These legacy coatings have been identified on the OSD Emerging Contaminants Watch or Action Lists, and future manufacture and maintenance o ...

This proposed project is to develop a novel class of high-temperature, high-energy-product permanent magnets with minimized rare-earth element based on a two-phase (Sm2Fe17N3)1-x(Co35Fe65)x (0

Quantum cryptography, and in particular Quantum Key Distribution (QKD) is a secure method to distribute a secret key between two distant authorized partners whose security is based on the laws of physics. Current public key cryptosystems have not been proven to be secure and are based on the computational complexity of evaluating one-way functions. These functions are easily evaluated, but extrem ...

ABSTRACT: There has been a growing interest and increased R & D activities in applying THz technology to biomedical, security, communications and science/manufacturing imaging, etc. However, even with all these research activities, there are very limited choices of test and measurement instruments in the THz range. Despite wide availability of RF/microwave (below THz) and optical (above THz) netw ...

We propose a compact, monolithic, power scalable, hollow core fiber-gas laser emitting in the atmospheric transmission region in the mid-IR. The proposed optically pumped fiber-gas laser system is efficient, has a small footprint as well has a broad spectral coverage in the mid-IR. Due to the unique approach employed, the proposed technology allows generation of mid-IR output with varying pulse re ...

FIRST RF will lead the Phase II effort and will leverage the system architecture of the MAINLINE system and integrate multifunctional SiGe integrated circuits (ICs) developed by The University of California San Diego under the supervision of Prof. Gabriel Rebeiz. The SiGe devices developed during the Phase II effort will significantly reduce the power requirements of the MAINLINE system allowing f ...

Current scene projection hardware is challenged to simultaneously meet the requirements for high peak temperature (> 2000K), high resolution (> 1Kx1K), response time < 1 ms, cryogenic and temporally uniform photon flux. MEMS, Resistor arrays, liquid crystals, and photonic crystals all suffer in one or more areas. MEMS suffer from flicker and low dynamic range. Resistor arrays suffer from low frame ...
