We present a new theory on the scattering of radiation by real fibers in engineering systems. The theory covers the scattering by fibers consistently over an entire range of fiber sizes, from smaller than to larger than the wavelength of radiation. A geometrical technique is presented for modelling a fiber with a rough surface of 3D-selfsimilar microstructure. Scattering characteristics of the fiber are described based on an electromagnetic wave theory of diffraction, in order to investigate the relationship among three main factors of scattering: wavelength of radiation, fiber diameter and microstructure of the fiber. It is clarified that with an increase in fiber diameter and a corresponding increase in rough fiber surface microstructure, the scattering changes from a particle scattering type to a surface scattering-type. The transition occurs in the size parameter range of P=100〜300.
