We show that surface waves can be guided on the exterior of an isotropic elastic bar with a rectangular cross section. We assume that the dimensionless wavenumber is sufficiently large that elastodynamic ray theory is valid. Dispersion relations are obtained and representative curves for various cross sections are shown.
