Mass density normalized extinction has been both measured and computed throughout the infrared for distribution of well-separated synthesized silver fibers. The computational basis is a code origi nally generated for use with Drudian thin fibers at millimeter wavelengths and modified for appli cation at wavelengths that include molecular and structural (crystalline) resonances as well as thicker fibers. The computation involved convolution of fiber responses over distributions for both fiber lengths and diameters. Agreement between the measured and the computed results was found to be close.

  16. With regard to randomization of fiber orientation: the fiber orientation orthogonal to the propagation vector yields the cosine squared average value of ½ while that in which the propagation vector is not orthogonal with the fiber produces a phase shift along the fiber and decays more slowly for an average of 2/3 producing a net average (product) of 1/3(J. C. Pedersen, Pedersen Research, Inc., 212 High Street, Newburyport, Mass. 01950, personal communication, 1995).
