A ray‐optical description for the surface wave contribution to the far fields radiated by an electromagnetic point source in the presence of a planar interface between two lossless, homogeneous, anisotropic media is formulated. The surface wave rays are viewed as extending radially along the interface from the normal projection of the source onto the interface. Locally, the ray fields are those of the modal surface waves carrying energy in the ray direction. The effect of anisotropy on the surface wave radiation pattern is also considered.
