Extinction efficiencies for metallic fibers in the infrared

Abstract

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.
