Abstract
The propagation of surface (Rayleigh) waves over a rotating orthorhombic crystal is studied. The crystal possesses three crystallographic axes, normal to the symmetry planes: the half¿space is cut along a plane normal to one of these axes, the wave travels in the direction of another, and the rotation occurs at a uniform rate about any of the three axes. The secular equation for the surface wave speed is found explicitly; in contrast to the non¿rotating case, it is dispersive (frequency dependent). Both Coriolis and centrifugal accelerations appear in the equations of motion: none can be neglected in favour of the other, even at small rotation rates.
