Summary

Non-stationary surface waves of the “diverging circles” type propagating along a surface of a right circular cone from a hexagonal monocrystal are refered to as such, when a cone axis coincides with a crystal's axis of isotropy. It is shown that on a free surface of such a cone there are two types of waves: horizontally polarized surface waves (non-stationary waves of the “whispering gallery” type) and vertically polarized surface waves (non-stationary Rayleigh waves). Velocities of these waves are received and the attenuation of their intensities during propagation is investigated. As an example, we take a cone from a zinc oxide single crystal.
