Abstract :
We analyze circumferentially circulating mechanical whispering-gallery modes [WGM] resonating in a micron scaled silica sphere. We recently showed that such modes can be excited optically. A variety of modes are calculated in which the deformation is polar, radial or azimuthal. Additionally, we calculate Rayleigh WGMs for which points on the surface follow a circular path.
