Rotational Waves
Rotational Waves : Motions of a continuum, where the rotational dynamics is present. Term sometimes used in connection with micropolar media to describe rotation waves in a medium in which each point has degrees of freedom related to rotational motions. It is important not to confuse rotational waves with rotational ground motions appearing as the curl of the wavefield in linear elasticity with a symmetric stress tensor (e.g., S waves)
