Author(s)
J G. Quintiere
Working with Forestry Canada and the Ontario Ministry of Natural Resources, the Defense Nuclear Agency carried out an extensively instrumented experiment of a prescribed burn in forest debris to simulate conditions of a mass fire. In addition to the

Laboratory Studies of Smoke Properties at NIST Past, Present, and Future

November 1, 1990
Author(s)
George W. Mulholland, Nelson P. Bryner
Burn facilities have been developed at NIST to measure the yield and optical properties of smoke at two fire scales. The small scale apparatus is used for burning samples about 10 cm in diameter (soup bowl size) and an intermediate scale apparatus is used

MMIC Package Characterization with Active Loads

November 1, 1990
Author(s)
K. R. Phillips, Dylan Williams
Abstract: A technique for characterizing microwave packages based on active PIN diode standards is discussed. The technique allows packages to be accurately characterized from external reflection coefficient measurements when a single bias-dependent active
