We present a new technique for measuring the magnitude and phase of intermodulation products outside the measurement bandwidth of our instrumentation. We apply
We introduce nonlinear large-signal scattering parameters, a new type of frequency-domain mapping that relates incident and reflected signals for sparse-tone
We propose a metric that quantifies the degree of nonlinearity of state-space trajectories. We use the metric to improve the selection of collections of
We propose two verification methods for measurements of noise parameters of amplifiers, particularly low-noise amplifiers (LNAs). One method is a direct

A new 16-term statistical calibration is developed for the correction of vector network analyzer (VNA) data. The method uses multiple measurments of gneric
We report on the development of a microwave power limiter based on high-temperature superconductor technology. The power limiter takes the form of a 50 ohm
There is a need for better data to improve our knowledge of human behavior in fire. This data can be used in the development and refinement of evacuation models

A spectrally tunable solid state source based on Light Emitting Diodes (LEDs) is being developed at the National Institute of Standards and Technology (NIST)
A near-ambient, variable-temperature noise standard whose physical temperature can be accurately measured was constructed and then measured with the NIST total

Research at the National Bureau of Standards (now the National Institute of Standards and Technology or NIST) involving the gas atomization of liquid metals has
Wide-ranging viscosity measurements of the blends RA410A (0.5 R32+0.5R125 by mass) and R507A (0.5 R143a+ 0.5R125 by mass) were carried out in a torsional
