Light-scattering Mueller matrix for a rough fiber

The light-scattering Mueller matrix for an r approximately 2.0 microm radius, rough quartz fiber contains phase information different from that of a perfectly cylindrical fiber of the same optical constants and radius. The rough surface creates higher-frequency, smaller-amplitude oscillations that mask the lowerfrequency oscillations indicative of a perfect cylinder. Roughness also causes scatter outside the plane of incidence.
