Evaluation of a Portable Hyperspectral Imager for Medical Imaging Applications

October 2, 2007
Author(s)
David W. Allen, Maritoni A. Litorja, Steven W. Brown, Joseph P. Rice, Yuqin Zong
Portable hyperspectral imagers are becoming commonly available as a commercial product. A liquid crystal tunable filter based CCD imager was evaluated and characterized for spectral stray light using a tunable laser facility. The hyperspectral imager is

The Direct Patterning of Nanoporous Interlayer Dielectric Insulator Films by Nanoimprint Lithography

October 2, 2007
Author(s)
Hyun Wook Ro, Ronald L. Jones, H Peng, Daniel R. Hines, Hae-Jeong Lee, Eric K. Lin, Alamgir Karim, Do Y. Yoon, D Gidley, Christopher L. Soles
Directly patterning dielectric insulator materials via nanoimprint lithography has the potential to simplify fabrication processes and significantly reduce the manufacturing costs for semiconductor devices. However, the prospect of mechanically forming

A Microfabricated Flow Controller for Refrigerant Expansion

October 1, 2007
Author(s)
David A. Yashar, Piotr A. Domanski, Don DeVoe
A flow controller for refrigerant expansion is reported. Devices are fabricated using a micromolding technique developed for thick nickel electroplating. The device consists of a short tube restrictor with an integrated normally-open valve which, when

A Numerical Method to Solve the Boltzmann Equation for a Spin Valve

October 1, 2007
Author(s)
J Xiao, A Zangwill, Mark D. Stiles
We present a numerical algorithm to solve the Boltzmann equation for the electron distribution function in magnetic multilayer heterostructures with non-collinear magnetizations. The solution is based on a scattering matrix formalism for layers that are

Absolute Magnitude and Phase Calibrations

October 1, 2007
Author(s)
Kate Remley, Paul D. Hale, Dylan Williams
In VNA measurements, the magnitude and phase of a transmitted or reflected wave are measured relative to that of the incident wave. VNA measurements are made a single frequency at a time and each frequency component is acquired relative to the internally

Development of genomic reference materials for Huntington disease genetic testing
