Light Scattering in Gold Nanorings

November 1, 2004
Author(s)
Javier Aizpurua, L A. Blanco, P Hanarp, D S. Sutherland, M Kall, Garnett W. Bryant, F J. de Abajo
The optical response of gold nanoparticles of disk-like and ring-like shape is studied by analyzing their extinctioncross section in the visible and near infrared regions. A strong dependence of the excitation modes on the actual geometry of the

Microstructure Evolution during Alternating-Current-lnduced Fatigue

November 1, 2004
Author(s)
Robert Keller, Roy H. Geiss, Yi-Wen Cheng, David T. Read
Subjecting electronic interconnect lines to high-density, low.frequency alternating current creates cyclic thermomechanical stresses that eventually cause electrical failure. A detailed understanding of the failure process could contribute to both

Microwave Power Imaging with Ferromagnetic Films Incorporated in Bimaterial Cantilevers

November 1, 2004
Author(s)
Thomas Mitchell (Mitch) Wallis, John M. Moreland, Billy F. Riddle, Pavel Kabos
We report an imaging technique that uses ferromagnetic films incorporated in bimaterial cantilevers for spatially resolved calorimetric detection of microwaves emitted by sources of high frequency (4 to 20 GHz) radiation. The ferromagnetic film absorbs

Modeling Reliability in Distributed Computer Networks

November 1, 2004
Author(s)
Christopher E. Dabrowski, Kevin L. Mills
Our results extending Kuhn's fault class hierarchy provide a justification for the focus of fault-based testing strategies on detecting particular faults and ignoring others. We develop a novel analytical technique that allows us to elegantly prove that

Multiport Investigation of the Coupling of High-Impedance Probes

November 1, 2004
Author(s)
Dylan F. Williams, Pavel Kabos, Uwe Arz
We used an on-wafer measurement technique that combines two- and three-port frequency-domain mismatch corrections in order to characterize the influence of a high-impedance probe on a device under test. The procedure quantifies the probe’s load of the

Nanotechnology with Atom Optics

November 1, 2004
Author(s)
Jabez J. McClelland, Shannon B. Hill, M Pichler, Robert Celotta
A brief review of atom optics is presented, with emphasis on how it can be applied in the field of nanotechnology. Two specific examples are discussed: laser-focused atomic deposition and deterministic production of single atoms. Results are summarized for

NIST/XDS Test Kit, Version 1.3 & 1.4

November 1, 2004
Author(s)
William J. Majurski, A Mccaffrey, Mary T. Laamanen
The National Software Reference Library (NSRL) of the U.S. National Institute of Standards and Technology (NIST) collects software from various sources and publishes file profiles computed from this software (such as MD5 and SHA-1 hashes) as a Reference

NNI Workshop Instrumentation and Metrology for Nanotechnology

November 1, 2004
Author(s)
Michael T. Postek, J J. Pellegrino
The NNI Interagency Workshop on Instrumentation and Metrology for Nanotechnology Grand Challenges was held on January 27-29, 2004 in Gaithersburg, Maryland, and was cosponsored by the National Institute of Standards and Technology (NIST), an agency of the

Ontology-Based Methods for Enhancing Autonomous Vehicle Path Planning

November 1, 2004
Author(s)
R Provine, Craig I. Schlenoff, Stephen B. Balakirsky, S Smith, M Uschold
We report the results of a first implementation demonstrating the use of an ontology to support reasoning about obstacles to improve the capabilities and performance of on-board route planning for autonomous vehicles. This is part of an overall effort to

Performance Evaluation of Low Rate WPANs for Sensors and Medical Applications

November 1, 2004
Author(s)
Nada T. Golmie, David E. Cypher, O Rebala
We examine the performance of multimodal biometric authentication systems using state-of-the-art Commercial Off-the-Shelf (COTS) fingerprint and face biometric systems on a population approaching 1,000 individuals. Majority of prior studies of multimodal

Photoassociative Formation of Ultracold Polar KRb Molecules

November 1, 2004
Author(s)
Svetlana A. Kotochigova, Eite Tiesinga, Paul S. Julienne
We investigate the effectiveness of creating polar ground state KRb molecules by two-color photoassociative spectroscopy. In this process the molecules are formed from ultra-cold samples of K and Rb. Focussing on spin-polarized atoms we show that an

PMD measurement techniques and how to avoid the pitfalls

November 1, 2004
Author(s)
Paul A. Williams
This chapter presents a practical guide to PMD measurements including descriptions of the various measurement techniques and discussion of their associated sources of measurement error. Methods for mitigating these error sources are also discussed.
