On the excitation of electromagnetic surface waves on a curved surface

The excitation and propagation of surface waves on a spherical inductive boundary are considered. The source is taken to be a vertical electric dipole. The circumferential attenuation rates of the various modes are discussed where it is indicated that the dominant mode is very similar to the trapped surface wave for a plane inductive boundary. The results appear to conflict with those of Barlow, but are in sympathy with some numerical data of Elliott for the circumferential attenuation rate of the dominant mode.
