Theoretical Study of Single and Multiple Scattering by Cylinders.

Abstract

Closed form analytic results are obtaned for the calculation of the electromagnetic differential and total scattering, absorption, and extinction cross sections of arbitrarily oriented conductive fibers. An extensive computer program has been developed for the computation of these quantities. The results agree with expectations for arbitrary conductivity, arbitrary length-to-wavelength ratio and radius-to-wavelength ratio less than 0.3. Two minor exceptions are noted and discussed. The albedo of the particle is computed as are the appropriately averaged differential scattering cross sections. These quantities serve as inputs to a Radiative Transfer computer program which was developed concurrently to calculate and plot the angular distributions of reflected and transmitted radiation from large aggregates of the particles.
