Uncertainty of timebase corrections

Author(s)
Chih-Ming Wang, Paul D. Hale, Dylan F. Williams
We develop a covariance matrix describing the uncertainty of a new timebase for waveform measurements determined with the National Institute of Standards and

Spectrum Simulation in DTSA-II

Author(s)
Nicholas W. Ritchie
Spectrum simulation is a useful practical and pedagogical tool. Particularly with complex samples or trace constituents, a simulation can help to understand the

The coefficient of thermal expansion of highly enriched 28Si

Author(s)
Ernest G. Kessler Jr., Guido Bartl, Arnold Nicolaus, Rene Schodel, Peter Becker
For the new definition of the SI-unit mass based on a fundamental constant, a redetermination of Avogadro s constant is the goal of an international

Catherine A. Remley
This is an Editorial for the October, 2009 issue of IEEE Microwave Magazine. Kate Remley, the Editor-in-Chief, writes about timely topics for the members of the

Photomask metrology using a 193 nm scatterfield microscope

Author(s)
Richard Quintanilha, Bryan M. Barnes, Martin Y. Sohn, Lowell P. Howard, Richard M. Silver, James E. Potzick, Michael T. Stocker
The current photomask linewidth Standard Reference Material (SRM) supplied by the National Institute of Standards and Technology (NIST), SRM 2059, is the fifth

Thermal Diffusivity of H2O near the Critical Point

Author(s)
Jan V. Sengers, Richard A. Perkins, Marcia L. Huber, Bernard Le Neindre
The asymptotic critical behavior of the thermal diffusivity of H 2O, deduced from dynamic light-scattering measurements, is shown to be in good agreement with

Micromachined resonators of high Q-factor based on atomic layer deposited alumina

Author(s)
Atif A. Imtiaz, Yuan-Jen Chang, Jason M. Gray, Dragon Seghete, Steven George, Thomas Mitchell (Mitch) Wallis, Pavel Kabos, Charles T. Rogers, Victor M. Bright
In this paper, atomic layer deposited (ALD) alumina (Al2O3) has been demonstrated as the structural material for a micro-resonator for the first time.  An
