NIST has delivered a portable and highly accurate instrument for measuring mass to the U.S. Army, marking the first time in the U.S. that this technology is
Perched atop a high plateau in Chile’s Atacama Desert, a long-awaited observatory is beginning to take shape: the largest suite of ground-based telescopes
Physicist Jun Ye has a knack for making every second count—literally. At JILA, a joint research institute of the University of Colorado and the National
We have a number of opportunities to collaborate with us. See below for details. What does this project aim to do for the chemical industry? Many industrial processes depend on the intermolecular environment- the solvents and ions that surround a molecule. These interactions impact separations
The primary goal of this program is metrology that enables advanced nanoscale device (including electronics, spintronics, and life science) development. Based on current trends in electronics, we are focusing on metrology for two classes of devices: (1) nanoscale devices utilizing and exploring new
The Wireless Systems Metrology Program supports the growing wireless industry by developing methods to test the operation and functionality of wireless devices in the presence of various types of distortion. This includes multipath distortion, ranging from a line-of-sight environment (low-multipath)
Over the past several years, we have focused on bolometric detection of THz radiation. Our initial work on cryogenic detectors has been extended to antenna-coupled bolometers operating at room temperature. These detectors provide a rugged, low-cost alternative for homeland security applications; e.g

Standard formulations of error vector magnitude compare a wireless device's symbol constellation to an ideal reference constellation. In this work, we utilize
NIST Microwave Uncertainty Framework (Beta version) The NIST Microwave Uncertainty Framework provides a "drag-and-drop" toolkit for managing the calculation of
The Large Aperture Scanner (LAS) scans a radar transceiver over a 5 meter by 20 meter aperture. Image reconstruction techniques enable a three-dimensional
