Launching Efficiency of the HE/sub 11/ Surface Wave Mode on a Dielectric Rod

The excitation of the dominant HE/sub 11/ mode by a transversely oriented electric dipole on the axis of an infinitely long dielectric rod is studied. The method of analysis involves expressing the fields and the source in a Fourier integral in the z direction and a Fourier series in the /spl phi/ direction in a cylindrical coordinate system (/spl rho/,/spl phi/,z). The practical significance of the present study, in particular regard to the excitation problem in dielectric surface waveguides, is emphasized.
