ABSTRACT

The electromagnetic field statistical problems in region of random media with a boundary, particularly, in a region where two spaces separated by a boundary and possess coupling characteristics, have not been investigated completely. Also the anisotropic inhomogeneities in the refractive index and the unevenness of the boundary surface affect the transmission characteristics. The objectives of the present studies are to deal these practical problems as statistical problems of electromagnetic field in random fiber with anisotropic media. In this paper, by introducing a symbolic operator, the statistical nature of the electromagnetic fields of an open-type dielectric waveguide with anisotropic random refractive index is discussed. The eigen electromagnetic fields are derived for the case of random medium and the transmission equations are shown. The scattering losses and statistical guided modes are also shown by using statistical Green's dyadics with boundary effects and multiple scattering, for various correlation lengths of irregularities of anisotropic index inhomogeneities.
