Scattering and mode conversion of guided modes of a slab waveguide by a circular cylinder
Using expansions of modes of the dielectric slab waveguide in terms of the cylindrical functions, the scattering and mode conversion of guided modes by a circular dielectric cylinder are analysed approximately; mode conversion coefficients, total scattering power, and scattering power patterns are obtained. Some representative numerical results are presented for the case of scattering by a circular cylinder located in the surrounding outer region.
