Propagation of electromagnetic waves through a homogeneous anisotropic column of a medium of infinite length is considered. This anisotropic column is surrounded by a coaxial homogeneous isotropic medium enclosed by a perfectly conducting metallic circular cylindrical waveguide. A magnetic current ring source is inserted symmetrically in the isotropic medium. Throughout the analysis the strength of the source is considered to be an arbitrary function of the polar angle. For this general problem the complete expressions for fields due to the source, power flow, and the dispersion relation have been studied. To solve a source problem, dyadic Greens functions for both point electric current source and point magnetic current source have been constructed in a formal way from the source free solutions of the appropriate Maxwells equations. These dyadic Greens functions can be used for any arbitrary source.
