A general discussion of the scattering of plane monochromatic waves by dielectric wedges precedes this paper. Numerical solutions of the problem of scattering by a dielectric wedge of finite cross section, with special emphasis on the divergent behavior of
Understanding suppression mechanisms of different fire-suppressing agents including CF 3Br (Halon 1301) and inert gases is useful for their efficient use and for developing new agents. Because of the similarities between unsteady jet diffusion flames
This report addresses the thermal environment of the Howard StreetTunnel in Baltimore, Maryland, following the derailment in July 2001of a freight train and the burning of spilled tripropylene andthe contents of surrounding rail cars.A numerical fire model

Many of the projects managed by OMP are cooperative activities across several operating units. Thus the projects are able to leverage the best expertise available for the specific task across NIST, regardless of organizational structure. Our projects are
The accuracy and physical significance of the classical Rayleigh-Sommerfield and Kirchhoff diffraction integrals are assessed in the context of Sommerfield s rigorous theory of half-plane diffraction and Maxwell s equations. It Is shown that the Rayleigh
The NIST Optoelectronics Division provides measurement technology, standards, and traceability for the optoelectronics industry. This document describes the programs, activities, and accomplishments of the Division during the 2002 fiscal year. It is
