Modeling and metrology of metallic nanowires with application to microwave interconnects

May 23, 2010
Author(s)
Kichul Kim, Thomas M. Wallis, Paul Rice, Chin J. Chiang, Atif A. Imtiaz, Pavel Kabos, Jintao Zhang
Abstract: Broadband characterization of individual metallic nanowires for microwave interconnect applications is discussed. Circuit and method of moments (MoM) modeling are benchmarked using a set of coplanar waveguide (CPW) test devices with microwire Au

Third-Order Intermodulation Distortion due to Self-heating in Gold Coplanar Waveguides

May 23, 2010
Author(s)
Eduard Rocas, Juan C. Collado Gomez, Nathan D. Orloff, James C. Booth
We present measurements and modeling of a self-heating mechanism responsible for third order intermodulation distortion in coplanar waveguide transmission lines. Temperature fluctuations, at the envelope frequency of the input signal, induce dynamic

An Evaluation of Technologies for Knowledge Base Population

May 21, 2010
Author(s)
Hoa T. Dang, Paul McNamee, Heather Simpson, Patrick Schone, Stephanie Strassel
Previous content extraction evaluations have neglected to address problems which complicate the incorporation of extracted information into an existing knowledge base. Previous question answering evaluations have likewise avoided tasks such as explicit

Core-shell composite of SiCN and multiwalled carbon nanotubes from Toluene dispersion

May 21, 2010
Author(s)
John H. Lehman, Katherine E. Hurst, Gurpreet Singh, Elisabeth Mansfield, John D. Perkins, Christopher L. Cromer
Carbon nanotubes are known to have high thermal conductivity, and in bulk form, a topology that could constitute the matrix of an inhomogeneous solid. Among the promised applications of carbon nanotubes is a composite material that is practical for thermal

A Graphical Approach for Assessing High Strength Fiber Performance

May 20, 2010
Author(s)
Walter G. McDonough, Gale A. Holmes, Amanda L. Forster, Kirk D. Rice
The design and materials used for bullet resistant body armor have evolved continuously to keep up with the threats. In this paper, a graphical approach is presented that plots the potential strain energy absorption of some common high performance fibers

CCEM.RF-K4.CL Comparison RF-Voltage measurements up to 1 GHz

May 20, 2010
Author(s)
James P. Randa, Jan P. de Vreede
We report the results of an international comparison of measurements of radio frequency voltage in the frequency range 1 MHz to 1 GHz. This comparison was performed as a Key Comparison under the auspices of the Consultative Committee for Electricity and

High Speed Fiber Testing: The Single Fold Test

May 20, 2010
Author(s)
Haruki Kobayashi, Walter G. McDonough, Alexander J. Shapiro, Jae H. Kim, Stefan D. Leigh, Amanda L. Forster, Kirk D. Rice, Gale A. Holmes
The failure of a first responder s body armor has prompted research to assess the long-term durability and effectiveness of current and future soft body armor products. Prior work in this laboratory described a 10 % drop in tensile strength and 15 % drop
