The fields scattered by a homogeneous dielectric or finitely conducting object can be obtained from two tangential vector fields, the components of the electric
At the National Institute of Standards and Technology, the goal of the program in Manufacturing Simulation and Visualization is to accelerate the development of
I gaze into a somewhat cloudy crystal ball to predict the directions of electrical metrology in the next fifteen years. The emphasis on standards based on
The emergence of several radio technologies such as Bluetooth, and IEEE 802.11 operating in the 2.4 GHz unlicensed ISM frequency band may lead to signal

We describe the development of a cryogenic thermal transfer standard (CTTS) from the first prototype in 1997 to the present version. A description of the
Simulation technology holds tremendous promise for reducing costs, improving quality, and shortening the timeto- market for manufactured goods. Unfortunately
Motivated by recent experiments on filled polymer thin films, we study the effect of the presence of filler particles on phase separating mixtures. using a

The recent status of the experimental studies of plasma broadening and shifts of non-hydrogenic neutral atom and positive ion spectral lines is reviewed and the
The difficulty in manufacturing Rockwell diamond indenters to the required geometric specifications has resulted in most commercially manufactured indenters to
We show that the dispersion of optical components can be determined from a single low-coherence interferometric measurement. This technique can be applied to
A new system to characterize the magnitude and phase characteristics of 1 pF to 1 uF capacitance standards over the 50 Hz to 100 kHz frequency range is

Dynamic compact electrothermal models are developed for Silicon Carbide Power diodes. Model parameters are extracted and model results are presented for both
Electronic projection display specifications are often based on measurements made in ideal darkroom conditions and assume ideal measurement instrumentation
The accuracy of tristimulus colorimeters can be increased by using detector standards instead of traditional lamp standards for calibration. After high accuracy
We need to facilitate a change in user perception of security from a hindrance to an essential revenue generator and mission enabler. The Common Criteria

The basic goal of the Advanced Optics Metrology program at NIST''s Manufacturing Engineering Laboratory is to help industry ensure that their measurement
The National Bureau of Standards (NBS) was formed by Congress 100 years ago. The early Bureau was a small organization, founded at the beginning of the age of
